This reminds of the that friends episode where Julia Roberts runs off with Chandler's clothes in the restaurant restroom, forcing him to wear her underwear:
Phoebe: You know, I think I want to write a song about all this.
Rachel: Oh yeah?
Phoebe: Yeah. Oh, except one of the strings on my guitar is broken. Hey, Chandler, can I borrow your G-string?
Chandler: How long you been waitin' to say that?
Phoebe: About 20 minutes.
