Dex: You're just being paranoid. Again.
Zap: When have I ever been paranoid?
Dex: Um, when you first met Tung and thought he was an undercover cop...?
Zap: No one has a wart that big, I thought it was a surveillance camera!
Dex: And last year you were sure Jenny was a mermaid!
Zap: She hates wearing tight shirts! COINCIDENCE?!
[Later when Zap's theory is proven wrong]
Dex: Do you have anything to say?
Zap: I still think Jenny is a mermaid.
