"WHAT?" Mindy screamed.

"Mona? What are you talking about?" asked Joey, still in shock.

"Well, you know the time when we, uh, well I pregnant."

"You cheated on me you sick bastard?"

"Look Mindy. It was just one thing and it meant nothing to me."

"Oh really?" said Mona.

"No, I mean you mean a lot to me but I love Mindy."

"Joey Tribbiani, I would never marry you."

"No, Mindy please just think about how much I love you."

"No Joey," she started crying. "I loved you so much. I'd thought you'd changed. I was about to say yes. I have to go."

"Mindy, wait. Please give me another chance."

"Joey. I can never forgive you for this because I'll always picture you with that slut."

"Hey," snapped Mona. Mindy left and Joey sat down. "Sorry I ruined your proposal."

"It's okay. So, we're having a baby!"

"Yeah. Joey you can be as involved as you want. I'm not asking for anything."

"Mona, this is my child too. I want to be involved. How did this even happen?"

This is a flashback of when Joey and Mona slept together

"Hey Joey," said Mona as she walked into Central Perk.

"Hey. What's up?" Joey always had a small crush on Mona but never said anything because she was Ross's fiancée.

"Not much. I kinda had a bad day. Have you seen Ross?"

"Yeah, he was over at my place talking to Rachel. C'mon I'll take you."

"Great! Thanks." When they got to his apartment, Ross wasn't there.

"Oh, by the way," said Joey, "you never told me why your week was so bad."

"Well, things at work are bad and, um, this is kind of embarrassing, but I haven't had sex in three months."

"Wha-what?" He was so turned on.

"Well, you know, Ross has either been working late, grading papers or just been really tired and any other time we're planning the wedding. I'm about to burst!"

"It can't be that bad."

"Oh, it is. I can't…." Suddenly Joey's crush got the better of him and he kissed her and she kissed back fiercely. Within minutes they were having sex.

"Shit. I can't believe I did this," Joey said. "Ross is my best friend."

"Joey, please let's not talk about Ross. That was unbelievable."

"Obviously. You had sex with me. Can we keep this to ourselves? Please."

"Yeah, sure."

Back to regular time…

"So, uh, I guess we have to tell Ross," said Joey.

"Yeah, I guess," answered Mona. They went to Ross's apartment with a dinosaur model for if he got too mad.

"Ross," said Mona, "can we talk to you?'

"Yeah, c'mon in."

"Ross please don't get mad," said Mona, "but, um, I'm pregnant."

"Honey. That's great!"

"With Joey's baby."

"WHAT?"

"Well, honey, you were always working and God Ross we haven't had sex in such a long time."

"Yeah and she came to me and we couldn't help ourselves," said Joey.

"I just can't believe this. I thought you were my friend," Ross yelled, "How could you do this?"

"Ross I'm sorry. We were both really depressed and we couldn't think well."

"Look, I really don't want to talk to you right now, Joey, I want to talk to Mona, alone." Joey left. He felt so bad about what he'd done to his best friend.

"Mona, I thought you loved me!" Ross shouted.

"I do love you. It's just that you were to busy for me and I, well, need to be satisfied."

"What the hell you slut, couldn't you have talked to me?"

"Why is everyone calling me a slut?"

"Hmmm, good question," Ross said sarcastically.

"I'm sorry. But, we would be taking care of this baby together. I mean Joey would be there but…."

"Wait a second. You actually think I'm gonna take you back?"

"Please Ross. I love you."

"What are you crazy? You cheated on me with my best friend. I think you should go now."

"But Ross…"

"Leave."

"Okay, I'll go. But wait hold on. I never stopped loving you. It's just, I felt like I wasn't important to you anymore."

"No, you were horny and wanted to have sex so much that you thought you could get away with this."

"How could you say that after the whole 'we were on a break' thing with Rachel?"

"That was different. We were broken up, I was drunk, Chloe was not Rachel's best friend and she didn't have my baby. And, also, I was gonna tell her about sleeping with Chloe. You were never going to tell me so get out of my house." Mona left and Ross was left heartbroken. He thought that this must have been how Rachel felt when he cheated. At that moment he realized why he was constantly getting dumped and divorced: he always loved Rachel and his love for her had sabotaged every relationship he'd had, except for Carol.

Meanwhile, Mona went over to Joey's apartment.

"Mona, hi."

"Joey, we have to talk. So what are we going to do?"

"About what?"

"The baby, we're having a baby. I mean, do you want to get married?"

"I don't know. I want to but I can't do that to Ross.

"Yeah, okay. I guess you're right." She kissed him and told him that she was going to go to the doctor tomorrow. She kissed him again but the only things going through his mind were the haunting six words: 'You're going to be a father.'
