KK, if I don't miss my guess, you're referring to scene 23.
Scene 23: Inside the Stateroom aboard Ship
Kurt: Hon, did you put this tape on the door?
Goldie: What tape?
Kurt: This tape.
Goldie: No, why would I put tape on the door?
Kurt: That's why I asked. Nevermind, hand me that ruler. (Goldie hands ruler to Kurt.) Aha! Just what I suspected. It's seven and a quarter inches long.
Goldie: So?
Kurt: Well, if it were any less, the person who left it here would only be a dingleberry. But seven and a quarter inches of scotch tape is the true sign of an @ssh@t.
Goldie: What's an @ssh@t?
Kurt: Well, it's sort of, ummmm...well one forum member called it an act of douchebaggery, and you know what a douchebag is, don't you?
Goldie: Of course, but who put the tape there?
Kurt: That's what I'm going to find out.
Goldie: Why don't you just put some Goo Gone on it?
Kurt: THINK WOMAN! We're in the middle of the ocean. Where am I going to find Goo Gone?
Goldie: Do you think Julie the cruise director might have done it?
Kurt: I don't think so. Besides, she's usually so coked up I don't think she could manage it, although if she did, it'd be just like her to forget to attach the note.
Goldie: Could Captain Stubing have done it?
Kurt: Right..mmmmmmm...Gavin Macleod. I never trusted him.... (Goldie and Kurt look at each other thoughtfully as the theme music comes up.)
