Niles: See you later, Dad. Great day.
Frasier: All right, how bad was it?
Niles: Mortifying. First of all, he refused to go nude, even in the private rooms.
Frasier: Well, Niles, don't forget, Dad is of a different generation.
Niles: Wearing socks and underpants and carrying a wallet into a mud bath is not a generational issue. If you ever hear me offer to take Dad to a spa again, wash out my mouth with jug wine.
