Mitchell: What are you doing here?
Langham: You gave me your room key.
Cameron: What?!
Langham: Don't act so shocked. You told me at the bachelor party you two lead separate lives.
Mitchell: You went to the bachelor party?
Cameron: Yes, and I was starting to feel bad about sneaking around, but I guess I shouldn't have, now that I see what you're up to.
Mitchell: I'm not up to anything! I left my key by mistake.
Langham: We're all obviously tense. Let's take a deep breath, get in the tub-
Mitchell: That's not happening.
