Frasier: For some reason, you know, just because the man was in prison he seems to have marked him for life.
Niles: It's ridiculous. Not all criminals are recidivists. I've seen many cases where after they've paid their debt to society they've gone on to lead productive lives. Dad's just being narrow-minded.
Frasier: Hmm. Yes, I almost had to sedate him when Daphne announced that she was going to go out with him.
[Niles laughs. Twice.]
Niles: Frasier, I hope you're just yanking my giggle chain.
Frasier: What do you mean?
Niles: You're telling me that you're letting this delicate English rose be sullied by some sociopath?
Frasier: Niles, he passed bad checks. He's not a sociopath.
Niles: He's a degenerate who should be put away forever!
Frasier: You haven't even met him.
Niles: Oh, for God's sake, they're all depraved animals!
