Daphne: Well, I think you make a lovely couple. Even though Niles can't believe you're dating a gym teacher. He says it's a betrayal of your younger selves.
Frasier: Yes, it's perfectly understandable. We didn't have much luck with gym teachers when we were kids. They were always so derisive and ego-crippling. There was this one in particular, Coach Fuller. He was the worst. The kind of man that would make the whole class wait while you did your push-up. It was so traumatizing, you know, I would actually lose my lunch before gym period. Except on those days when my lunch money was stolen. Then I'd just dry heave.

Frasier: Ooh, Niles, sorry I'm late. Did you sign us up?
Niles: Um, Frasier, I've been thinking. How many years have we teamed up for the squash tournament, only to be eliminated in the second round?
Frasier: Nine.
Niles: Don't you think it's time we came up with a new strategy?
Frasier: Niles, if you're talking about taking that powder that's made from sheep's glands, the answer is never again.

Frasier: You know, when I heard you shouting at that little girl today, I swear, it just brought back a flood of memories from my own childhood.
Chelsea: Really?
Frasier: Oh, yeah. You know, my gym teacher was constantly yelling at me because I couldn't do a single pull-up, or a lap around the track.
Chelsea: Not even one?
Frasier: Oh, please. I was a very late bloomer. I could barely do a jumping jack without getting a nosebleed. And let's not begin to talk about the climbing rope.
