[Scene: ATM vestibule, Jill Goodacre is on the cellular phone. Chandler's thoughts are in italics.]

Chandler: Oh my God, it's that Victoria's Secret model. Something... something Goodacre.

Jill: (on phone) Hi Mom, it's Jill.

Chandler: She's right, it's Jill. Jill Goodacre. Oh my God. I am trapped in an ATM vestibule with Jill Goodacre! (pause) Is it a vestibule? Maybe it's an atrium. Oh, yeah, that is the part to focus on, you idiot!

Jill: (on phone) Yeah, I'm fine. I'm just stuck at the bank, in an ATM vestibule.

Chandler: Jill says vestibule... I'm going with vestibule.

Jill: (on phone) I'm fine. No, I'm not alone... I don't know, some guy.

Chandler: Oh! Some guy. Some guy. 'Hey Jill, I saw you with some guy last night. Yes, he was some guy.

(Chandler strides proudly across the vestibule and Jill stares at him.)

[Scene: Monica and Rachel's, time has passed. The five are sitting around the coffee table talking.]

Rachel: Alright, somebody.

Monica: OK, I'll go. OK, senior year of college... on a pool table.

All: Whoooaa!

Ross: That's my sister.

Joey: OK... my weirdest place would have to be... the women's room on the second floor of the New York CIty public library.

Monica: Oh my God! What were you doing in a library?

Ross: Pheebs, what about you?

Phoebe: Oh... Milwaukee.

Rachel: Um... Ross?

Ross: Disneyland, 1989, 'It's a Small World After All.'

All: No way!

Ross: The ride broke down. So, Carol and I went behind a couple of those mechanical Dutch children... then they fixed the ride, and we were asked never to return to the Magic Kingdom.

Phoebe: Oh, Rachel.

Rachel: Oh come on, I already went.

Monica: You did not go!

All: Come on.

Rachel: Oh, alright. The weirdest place would have to be... (sigh)... oh, the foot of the bed.

Ross: Step back.

Joey: We have a winner!

• the foot of the bed
• See the photo on the right.  That is the foot of the bed.
• What Rachel means was that she was less adventurous.  The weirdest place where she had sex was the foot of the bed; not far from the bed itself.
