In the season 7 episode where They All Turn Thirty, Rachel turns 30, while everyone else remembers their own 30th birthdays in the past. We get only a brief glimpse of Chandler's birthday in that episode, but he later complains to Joey, "For my last birthday, you gave me a hug."

I'm only guessing, but I'm going to set Chandler's 30th birthday in late season 6. There are a couple of episodes in the show which suggest that Chandler's birthday is in April. In 518, the gang throws Rachel a surprise birthday party a month early, and she remarks that "Chandler's birthday is even before mine!" In 617, two weeks after Valentine's Day, Monica mentions to Chandler, "Your birthday is in a month-and-a-half."

Chandler's 30th birthday party wasn't much fun. For one thing, the chick and the duck weren't there, even to just drop by for five minutes. Monica just wouldn't back down on her ban, no matter what.

His other friends ruined his birthday party as well. Phoebe had continued to fight with Monica, and she also kept making jokes about Chandler being whipped and effeminate. It was mean-spirited rather than playful, and Chandler felt too bitter to give a sarcastic comeback.

Plus, Ross was upset that Rachel kept dating Elizabeth's dad, even though Ross found it uncomfortable. Just weeks earlier, Ross had briefly dated Rachel's sister Jill, but he had agreed to end it when Rachel insisted that it freaked her out. Rachel wouldn't do Ross the same courtesy, and her attempt to get Paul to like Ross hadn't worked at all. But still, she insisted that Ross had no right to tell her who to date.

"Then why do you have the right to make me back off?" he asked.

"Because that was my sister! It was creepy!"

"And this isn't!"

Chandler tried to be sympathetic to Ross's problem, but the argument was spoiling the party. Also, he found himself reminded of his unequal relationship with Monica. How she always made him compromise and give in to her will, but she wouldn't do him the same courtesy.

Joey was acting very weird and distant too. He got drunk and silently moped in a corner, and when they asked him what was wrong, Joey didn't want to answer. When they insisted, Joey just whined to God like he had whined at his own 30th birthday. "It's just... we're all getting so old! Why are you doing this to us! We had a deal."

They rolled their eyes and left him alone.

After cake, Chandler sat down to open his presents and get the horrible party over with. Monica's present was a package of filters for the water purifier. What the hell? And he couldn't even complain, or she wouldn't give him any sex tonight, even on his birthday.

Rachel had got him something obviously stolen from Ralph Lauren. Ross had bought him some ugly souvenir from his Spring Break trip with Elizabeth.

For her gift, Phoebe had composed a song about how Chandler was "the queen of everything" and she started to play it on her guitar. Great, more gay jokes at his expense! It wasn't funny anymore.

Chandler got up angrily and demanded that everyone leave.

"Wait, what about Joey's present?" Monica said. She actually looked cross at him, as if he were being rude and it was his fault that his party was such a disaster.

"Fine." He gritted his teeth. He turned to Joey and sighed, hoping that maybe his best friend might have got him something that could make up for this disappointing birthday. "Joe, what did you get me?"

Joey blushed and looked away, fidgeting in his chair. "Oh, um, I-I was gonna give it to you later."

Chandler was annoyed and hurt at first, but then he understood. "Oh!" He blinked and lowered his voice tactfully, "You haven't got paid for Mac & C.H.E.E.S.E. yet, right? Oh, that's okay, Joe. You didn't have to get me anything. Maybe next year." He moved to hug Joey tenderly.

Joey flinched and started to cry, though he turned away to hide his tears.

"Joe? Joey, you all right?"

Joey wouldn't answer, moaning while the others wondered whether Joey was just having another fit about his deal with God to not get older.

Chandler decided to escort Joey back to his apartment. "Come on." He put an arm around him and pulled him out of the chair.

Monica and the others started to clean up after the party.

At Joey's apartment, Chandler even walked Joey to his bed so he could sit down and hold Hugsy for comfort. "It's okay."

Joey felt bad and tried to apologize to him. "I-I really was gonna get you a present. I was! Not just a hug."

Chandler sat down on the edge of the bed. "Yeah? What were you gonna get me?"

Joey hesitated, looking worried, but then he said, "I-I was gonna get you an arcade game."

Chandler cheered up considerably. "Yeah? For a game room? Wow, that would be great!" But then his face fell. "Oh, but--but, Monica wouldn't let me have it."

"I could keep it for you, here."

Chandler laughed happily and hugged Joey tightly. "Of course! Thanks, Joe."

Joey got uncomfortable again and pulled away, clutching Hugsy.

Chandler thought he was just sad to not have the money yet, so he patted Joey's arm reassuringly. "It's all right, Joe. You can get it for me later, when you have the money. We can pick it out together. Should we get Space Invaders or Asteroids?"

Joey was too sad to be excited, and he broke down again.

"Joe?" Chandler moved closer.

Joey wept wretchedly and hid behind Hugsy. He whispered, "I-I miss you, Chandler. I wish you still lived here."

Touched, Chandler looked very serious and nodded. "I wish I did too."

"Yeah?" he looked up at Chandler through his tears and wondered if Chandler might come back to him.

Chandler hugged him again and added, "But don't tell Monica."

At her name, Joey moaned and turned away. He lay down and pulled the covers over him.

Chandler was concerned and wouldn't let go of him. He leaned over Joey and asked him what was wrong.

Joey told him to just go back to his party, but Chandler shook his head firmly. "No way! Come on, what is it? Are you just thinking again about--about when I moved out, huh? The end of an era?" Chandler remembered how much Joey had cried then, and made up silly nicknames for them, like J-man and Channie. It was actually kind of comforting to know that he meant that much to Joey. "I'm still here, Joe. I'm still here for you."

Still crying, Joey couldn't take it anymore, with Chandler so close. "I-I remember," he whispered.

"What?" Chandler rubbed his arm soothingly.

"That night, when we..." Joey trailed off and gulped, unable to say it. So he pointed to his bedside table, where the video camera and the tape rested. "I-I found it."

Chandler didn't understand. "What? The camera?"

"The tape," Joey said, then broke down crying again.

Chandler remained confused, but guessed that the tape must be something important. So he picked up the video camera and put the tape in to play it.

It took him a little while to recognize the contents, but when he remembered, he stared in horror and nearly dropped the camera. He thought that this tape didn't exist, that it had been erased, but here it was, out of nowhere.

It was a video of their first night in London. After going through customs and leaving the airport, Joey, Chandler, Monica, Ross, and the Gellers finally checked into the Marriott at around 10:00 pm, London time. Feeling jet lagged after the six hour flight, Mr. and Mrs. Geller decided to go to bed, but the others wanted to go out on the town and have fun. The gang were still on New York time, and Joey wanted to try out his new video camera.

After dropping off their luggage in the hotel rooms, the young friends hailed a cab outside and piled into the backseat. Joey already started recording with his video camera, getting shots of the cab.

"Where to, then?" asked their driver.

Monica said, "Well, we're not sure yet, sir."

"Call me Angus."

"Angus?" Joey found that a odd name.

"It's an old Scottish name," Angus explained to his camera. "But I was born and bred here in London."

Monica continued, "Well, Angus, we hoped that you could recommend a place to us. Do you know any good pubs?"

Angus glanced them over and said that there were a number of good pubs in London, "but they all close in an 'our, though."

"What!" They were quite shocked, and Ross even glanced at his watch, asking what time it was, because maybe they had miscalculated the time-zone difference from New York.

"It's 10 o'clock," Angus replied. "I knew you lot must be from the States, from the way you talked. That's why I warned you. Americans always think that closing time's not until 2."

"Well, that's the way it is in New York, and we thought London would be the same."

"Why didn't Emily tell you?" Chandler asked.

Ross only shrugged, having been more concerned about discussing wedding plans with his bride lately.

Joey pouted and complained to their driver, "Yeah, what's wrong with you Brits? Don't you drink late?"

Angus said a little more gruffly, "Don't let the locals hear you talk like that, mate. And besides, we prefer to be called English."

Chandler shushed Joey for his outburst and told him to go back to videotaping, while the others sighed with disappointment. "Well, what are we gonna do now? Go back to our rooms?"

Angus said, "Well, if you want to drink late, you'd have to go to one of them clubs that stay open into the morning, but they're very expensive."

They conferred among themselves for a moment, then Ross said for them, "Well, maybe we won't stay out really late, then. We do have to get up in the morning. So I guess we'll try a pub, if you can recommend one."

"All right, then. Seeing as you've got less than an 'our now to drink, I'll take you to the nearest one with a decent pint."

So Angus drove them to a pub called the Wheatsheaf, where they got a table together and ordered pints of Boddington's from the barman. They toasted Ross on his wedding, then sipped the beer, which was bitter and distinctly different from any American brew.

"Good Lord, that's excellent beer!" Chandler said, and the others nodded in astonished agreement.

Joey even cheered, "London, baby!" yet again. He drank up his pint heartily and soon asked for another one.

His friends grinned and told him to slow down, but he replied that they didn't have much time before the pub closed tonight, so they might as well get as much Boddington's as they could. So Chandler and Joey got up to buy more pints from the barman and fetch them back to the table. When they returned from the bar, Chandler took his seat and joked about the English accent of the barman, who wanted to be called that, and not a bartender.

The others commented on Angus's accent too, and soon the friends were playfully doing their best impersonations of the cab driver, while Joey played back a little of his videotape to judge against.

As they joked around and enjoyed the superb beer, they all wished that Phoebe and Rachel could be here to enjoy it with them.

"But Phoebe shouldn't be drinking anyway, because she's pregnant," Monica said.

Joey then saw a hot woman at the bar and went over to flirt with her. She found him charming at first, until he made some not-so-subtle innuendos about using his camera to film a sex video of them back in his hotel room. The woman found this far too forward, and threw a drink in his face.

Joey slunk back to the table, while his friends laughed at him and recalled the time that they threw water in Joey's face because of his soap opera stalker. Chandler teased that maybe his "How you doin'?" line didn't work universally after all.

Emboldened by the beer, Monica also began flirting with an attractive local who kept eyeing her from the bar. Ross grew concerned about this, because this guy was a complete stranger. Monica reminded him that she always had a fantasy to fall in love with someone from a strange land, and it might is well be an Englishman.

"If you can live out my fantasy with Emily, so can I."

Joey and Chandler told Ross to relax; maybe all she wanted was just to get a hot date to take to the wedding, because her mother Judy had kept harping on her still being single, while Ross was getting married for the second time.

"I guess you're right." Still, Ross watched them talking from afar and wondered if he could get Emily to scrounge up a male friend to be Monica's date instead.

"You mean like one of those big rugby guys?"

Ross frowned and recalled how intimidating and tough those guys were. "Um, on second thought, maybe not."

Then Joey said that they ought to get Ross really drunk tonight, since he was getting married this weekend.

Chandler protested, "But we already had a bachelor party back home."

"I know, but if there's two best men, then why can't we have two parties? Besides, it just doesn't feel right, him going into his wedding without a hangover."

They laughed and shook their heads.

Everyone was still enjoying themselves immensely, when they heard the warning that the pub was about to close. They groaned and rose to get Monica and leave. However, Clive, the man she had been flirting with, said that he was going to a club next, and asked if they wanted to come along with him. (Actually, he only asked if Monica wanted to come along, but she included her friends in the invitation.)

So they all left and walked to a nearby club, which was indeed expensive to get into, but Joey insisted that the fine alcohol was worth it. So they went in together and claimed a table for their group, while a couple of them fetched drinks again.

As they sat down and drank, Clive said that, because they came when the club first opened, it wasn't very crowded yet, nor was it too loud.

Joey, Chandler, and Ross had recently been to a very loud, very hip club in New York, and they said that they preferred their clubs to be more quiet and relaxed.

They all chatted about London for a while, and about Ross's wedding.

Then the live band on the stage started playing louder rock music, and groups of people jumped up to dance on the open floor.

Joey pointed his camera at the band and at the lively dancing. Clive asked Monica to dance, so they joined the crowds and enthusiastically bopped to the beat. Ross also decided to dance, to keep an eye on them, and they danced as group.

Chandler at first was too shy to dance, so Joey told him to hold the camera for him while he joined the others. Joey danced on the edge of the group, while keeping on the lookout for any attractive single women that he could mingle with.

After a while, Chandler felt lonely at the table and had enough drinks to decide that he ought to take a turn as well. So he got up and passed the camera back to Joey, then danced quite comically, flailing his limbs while Joey recorded him and laughed.

But surprisingly, Monica and Ross actually topped Chandler in bad dancing that night. When the band took a break later and the dj put on some retro '80s music, Ross started doing silly dances from his geeky youth. Monica followed her brother's example and played up to Joey's camera, while hoping to impress Clive with her moves.

Soon Monica and Ross even started doing a dance routine from their childhood that was incredibly dorky and embarrassing. Many people in the crowd turned and stared at the siblings in wonder; Clive laughed, thinking they were kidding around. But Monica felt hurt and angry, so she stormed off the dance floor without finishing the routine. Clive tried to apologize, but she wanted to go, grabbing her purse and heading for the door.

The rest of the gang decided that they better go back to the hotel now, so they left the club and hailed another cab. At the Marriott, Monica and Ross still discussed their dance routine as they headed upstairs. They felt perplexed as to why people would stare and laugh, but they decided that maybe British people just had different tastes in dancing.

Chandler meanwhile was so drunk by that time, that he couldn't even walk properly. Joey supported Chandler with one arm as they went back to their shared room, and then he casually pushed Chandler onto one of the two beds. He couldn't remember now which ones they had agreed to sleep in. "You okay, or you think you need to throw up?"

"I'm great!" Chandler replied and lay back against the pillows with a goofy smile.

At that time, the videotape in Joey's camera ran out, so he took it out and put a new blank one in. Then he got an idea and sat down on Chandler's bed excitedly. "Hey, hey, Chandler! Let's make a tape for the chick and the duck."

"What? Why?"

"Come on! It'll be cool." Joey resumed recording and pointed the camera at his face. He waved to the lens. "Hey, guys! We miss you! I hope you're having fun with Phoebe and Rachel!"

Chandler laughed. "What, are you gonna mail this home to them? I bet we'll get home before the tape does."

Joey turned to face him. "Maybe you could put it on your computer and email it to them."

"I didn't bring my laptop."

"Aw! Why not? You only use it for games and porn."

Chandler laughed and shrugged. "I didn't wanna lug it here, or lose it. Besides, I don't know how to hook up a camera to my computer."

"Aw, man. But there must be a way. How do all those porn videos get on the internet?"

Chandler just laughed. "I don't know."

Disappointed, Joey put down the camera on the nightstand, but he forgot to turn it off. "Well what are we gonna do now? I don't want to go to sleep!"

"I don't know. Let's watch TV."

"Oh, oh! Let's rent some porn!"

Chandler chuckled.

Joey got an even better idea. "Oh, oh! We can get some hookers."

He laughed long and hard, almost hurting himself, before answering, "Al-always illegal, Joe."

Joey looked let down again. "Really? But we're in another country. It doesn't count."

Chandler mocked Joey for his crazy logic, and Joey mocked him for his crazy dancing at the club. They both laughed, and Chandler teased him with a fake accent, "Yeah, guv'nor. We drive on the wrong side of the road, and 'ookers are legal!"

Joey shoved him lightly, and Chandler shoved back, until they started wrestling on the bed. Joey tickled Chandler until he was breathless.

Chandler fought him off at last, then Joey lay back and smiled at him fondly. "We're gonna have the best time in London! We're gonna see all the sights, and we're gonna rent Die Hard..."

"And we're gonna drink more Boddington's!" Chandler added, finally catching his breath.

Joey agreed and cheered, "Yeah! London, baby!"

Chandler nodded at the now familiar phrase, but felt bad for how irritable he had been on the flight to London. He met Joey's eyes and murmured, "Hey, I'm--I'm sorry I was mad on the plane, Joe. It was just, Monica being all intense about packing, and then her mom and dad looking at me weird the whole time, like they hated me..."

Joey understood. "Yeah, I know. And Mrs. Geller was kind of mean to Monica too. She kept saying that Monica was probably never gonna get married."

"Yeah," Chandler nodded and winced at that unpleasantness. He sighed in relief. "I'm glad you're here, Joe. If it was just me and the Geller family, I couldn't take it. I'd go nuts."

Joey grinned. "Hey, wouldn't it be cool if it was just us on this trip, huh?"

"Yeah. Just us. You and me." They looked at each other wistfully, as if imagining how perfect that would be. Chandler caressed Joey's cheek lightly, then Joey impulsively leaned in and kissed him.

He just did it, and enjoyed the softness and warmth of Chandler's lips. Closing his eyes, Chandler kissed him back and pulled Joey nearer. They kept kissing as if it was the most natural thing in the world, and they opened their mouths, tasting the beer on each other's breaths. They drank each other in, and Chandler sighed passionately, "Joe."

"I want you," Joey said and kissed him until he moaned. After making out for several moments, they started moving against each other and fumbling with their clothes. They both were becoming rather hot and breathless, still never knowing that they were being recorded by the camera. Unfortunately, before they could get naked or do much, their drunkenness overcame them and they passed out, although Joey stayed conscious a little longer, kissing Chandler's neck.

The video camera kept recording them until the tape ran out. That was their first night in London.
