Quote from Niles in Dad Loves Sherry, the Boys Just Whine
Sherry: Ooh, I love this apartment. Wow, that's some view you've got. Frasier: Thank you. Sherry: Which room's mine? [Frasier and Niles stare in horror] Gotcha! Martin: She's always doing stuff like that. Sherry: Oh, I love making people laugh. To me humor is like medicine. Niles: Guess we're in the placebo group.
