[Frasier is having doubts about his sexuality]
Frasier: I was sensitive as a child; I didn't go in for sports. God, it's every cliche in the book. Surely it must have occurred to you at some point? You refused to take me to see "West Side Story" on my eighth birthday.
Martin: Well, because of the gangs. That's scary for kids.
Frasier: Even gangs that dance?
Martin: Especially gangs that dance!
Niles: [demonstrating word association] Crescent... moon... Daphne Moon... French maid... brass bed... satin robe...
Frasier: This is my dream.
Niles: I was just showing you the process.
Frasier: You were three words away from a cigarette!
