Setup: This was originally supposed to be a part of The One With the Planetarium. So there is some background information you need to know. Firstly, Ross and Rachel are still married, but this time the baby's name will be Emma. Monica is not pregnant. Joey and Phoebe have been dating. So that is what remains the same (or has been changed) in this coming series.

Monica, Chandler, Joey, and Phoebe were sitting in their usual spots at Central Perk when Ross and Rachel enter holding their new baby, Emma. Ross asked Chandler and Monica if they could baby-sit Emma for the night while he and Rachel celebrated their one month anniversary. There wasn't anyone in the world that Ross trusted more than his baby-loving sister and his best friend.

"Oh sorry, we can't," said Monica. "Chandler has a business dinner tonight."

Ross was disappointed and was about to harass them further when Joey mentioned, "Well, I have no life. I can baby-sit."

"Oh, and I can come help after I'm finished with my massage clients," Phoebe chimed.

Joey added, "Oh, and I have the perfect gift for Emma when you bring her over. He was getting excited about the idea of baby-sitting with Phoebe.

"What is it?" Rachel asked.

"You'll just have to wait till you pick her up," Joey said coyly. "It's a surprise."

Ross was skeptical about letting the twosome baby-sit, but with his parents out of town and Chandler and Monica unavailable, he was getting desperate. "Well, thanks guys," Ross told them, "You are a life savor."

Ross and Rachel dropped Emma off at Joey's apartment, but he still wouldn't let them see the gift that he got for Emma. "I promise, it's nothing dangerous," Joey said as he tried to comfort them. Rachel had a hard time letting Emma go to begin with, but Joey's words did nothing to reassure her. Reluctantly, they went on their way to a quiet restaurant for dinner.

"This is nice," Rachel mused as she looked around. They were at a table for two with beautiful candelabras lighting their table. "We never get a nice quiet dinner by ourselves anymore."

"Yeah, it is a nice change," Ross agreed.

"Do you think it's too soon to call Joey and see if Emma's alright?" Rachel asked.

"Rach, they've only been alone together for half an hour," Ross said reassuringly.

"I know, but I mean, it is Joey," Rachel reasoned.

Without a second further of thought, Ross pointedly said, "Good point. I'll go call right now." He stood up and then immediately sat back down. "No, wait, we trust Joey. Carol went through this same thing the first time she left Ben with me. What could possibly happen?"

"Well, Joey could leave our baby on a bus," Rachel reminded Ross of when Chandler and Joey had left baby Ben on the bus when they were picking up women.

"Another good point," Ross agreed. "Joey doesn't deserve our trust. In fact, let's forget about dinner and get Emma now." Without any further thought, the couple stood up and left the restaurant.

Meanwhile, Joey was sitting in his apartment playing with Emma. He handed her his gift -- a stuffed lobster. "Here you go Emma," he said, "Now I'm going to tell you all about your parents so that by the time Aunt Phoebe gets here you'll be fast asleep. Now first your dad liked your mom but she didn't know. Then your dad went out with a girl named Julie when your mom liked your dad but he didn't know. When your dad found out he made a list and your mom got mad and wouldn't forgive him. Aunt Phoebe told your dad not to worry because she was his lobster-- thus the gift. Then your mom saw this prom video where your dad was going to save the day." As time past he got to the part where Ross and Rachel broke up, "Then they got in a fight because your dad said they were on a break…" Hours later, Joey finally concluded, "Then your mom found out she was pregnant with you."

Phoebe walked in just as he finished Ross and Rachel's long history. She looked in the crib and saw baby Emma sleeping with her stuffed lobster. "Aww, you got Emma a stuffed lobster," Phoebe cooed.

"Yeah, I was just telling Emma her parents' whole history and the meaning behind the lobster," Joey explained.

"That's so sweet. It explains why she's sleeping, but it's sweet." Phoebe said smiling.

Joey looked at Phoebe thoughtfully. As he gazed into her eyes, he told her tenderly, "Actually, I had planned on giving it to you originally. But I don't want our relationship to be like Ross and Rachel's, so I have something else for you instead."

"Really? What is it?" Phoebe asked excitedly.

"Okay, close your eyes." Joey told her. As she did what she was told, Joey reached down and picked up the duck and handed it to her.

"You're giving me the duck?" Phoebe asked confused.

"You're my duck," Joey told her.

Phoebe looked back at Joey blankly. "And you're my chick?" As she thought she added, "Wait a minute. I thought Chandler was your duck."

Remembering his conversation with the super, Mr. Treager, Joey reiterated, "What I said was that Chandler's nickname was duck."

Phoebe understood what he was saying, but still didn't understand the purpose of the duck. "So, why am I your duck?"

"Because Rachel is Ross' lobster, and you're my duck," Joey explained.

"I still don't get it," Phoebe told Joey.

Frustrated, Joey tried to explain further. "The Discovery Channel. After some documentary on jellyfish; I saw one on ducks. Did you know that ducks also mate for life?"

Phoebe finally felt she knew what Joey was saying, but couldn't believe that these kinds of words were coming out of his mouth. It was Joey of all people. "Are you saying that you want me to be your mate for life?" Phoebe asked.

"I don't know, but I certainly want to try," Joey told her.

"Does that mean we're going stead?" Phoebe asked excitedly.

"What are we, in high school?" Joey asked.

Somewhat disappointed with his response, Phoebe told him, "No, but I never went to high school. I never got to go steady with anyone."

That made sense to him. "Well, I guess we're going steady then!" Joey said happily and leaned into Phoebe for a lingering kiss.

Moments later, Ross and Rachel walked in to pick up Emma and caught Joey and Phoebe making out on the couch.

"So this is how you watch over our little girl?" Ross asked angrily.

Joey and Phoebe leapt off the couch, surprised by Ross and Rachel's presence. "What are you guys doing here? Shouldn't you be eating dinner?" Joey asked.

"Shouldn't you two be watching our baby?" Rachel asked accusingly.

"Relax, she's in the bedroom sleeping," Joey told the concerned parents.

Phoebe was too giddy to pay attention to the petty squabble around her. "I'm Joey's duck!" she said happily breaking the tension.

Ross stepped back, confused by her remark. "You're his what?" he asked.

"Duck. Jeez Ross, if you can have a lobster, I can have a duck." Joey told Ross.

Ross still didn't understand how they arrived at this conversation. "Umm, okay, good for you Phoebe," Ross told her.

"Ducks are better than lobsters anyway. At least we don't sit on the bottom of tank to get eaten," Phoebe rationalized.

The conversation had just gone from weird to weirder. Rachel whispered to Ross quietly, "I think we should just grab Emma and run."

"I was just thinking the same thing," Ross agreed. They turned to see Phoebe and Joey were back on the couch making out, so they crept toward the crib to rescue Emma.
