Niles: [on the phone] Frasier? You're too busy to answer the phone, but I'm just about to interview this... stripper, and I have no idea what to ask. I just hope Dad doesn't walk in and spoil the surprise. I'm already developing some sort of aversion-based mouth dryness as we speak. This is Niles, by the way.

Charlotte: Cell phones don't work here. Please tell me you know what's wrong with the car?
Frasier: Not a clue. I opened the hood as a mere formality.

Frasier: Can I get my usual, please?
Roz: Well, you're in a good mood. What's up?
Frasier: Well, actually... No, I better not. Don't want to jinx it.
Roz: No problem.
Frasier: Besides, the mark of a true gentleman is discretion.
Roz: Okay. Listen, about your dad's bachelor party...
Frasier: Charlotte and I spent the night together.
Roz: I thought she was seeing that super-hottie Frank.
Frasier: Dumped him, thank you.
Roz: For you? ... I mean, wow, way to go.
