- Josh: (on Paris Hilton claiming he talked trash about her) [Laughs] Am I talking about Paris Hilton? I never said anything about Paris Hilton, I'm sure.

We shot for 10 weeks, it was probably a 20-minute portion of the film, so yeah, it was probably 20 days, something like that. Yeah, I'm only wearing a towel and it seems like a big thing but when you're on set you've just got to give yourself over to the character. It was a funny idea.
