Phoebe: God, Joey, this is taking forever.
Joey: What's the rush?
Phoebe: Well, just- I have- I have an appointment and it's very important.
Joey: What is it?
Phoebe: Well ... it's a date.
Joey: A date? No, Phoebe, you must be mistaken, because I know you wouldn't schedule a date on the same night you have plans with a friend.
Phoebe: Come on, Joey, don't make me feel badly about this.
Joey: No, I'm gonna! That's right. Yeah. You made me feel really guilty about going out with that girl. Like I did something terrible to you. And now, Pheebs, you're doing the same thing.
Phoebe: It's not the same thing. This is totally different. This is with David. Remember David, the scientist guy? Okay, he's very special to me.
Joey: Okay. Well, my girl from the other night was special. She was a scientist too.
Phoebe: She was?
Joey: Well, she graduated high school.
