Sleeping with the Enemy - S3-E6

Character mistake: Noel Shempsky (the supposed Star Trek Nerd) attributes the quote "The needs of the many outweigh the needs of the few or the one" to James T. Kirk, when it was Spock who said it. (00:03:50)

Frasier: Niles, I would shave my head for you.
Niles: A gesture which becomes less significant with each passing year.

Trivia: John Mahoney plays Kelsey Grammer's father in the series, even though in real life he's only 15 years older than Grammer.
