Daphne: There must be some way to end this fight with your boss.
Frasier: What's the problem?
Martin: Oh, he wants me to date his sister and I won't do it so he's put me on graveyard 'til I cave.
Frasier: Well, he can't do that. Why don't you file a complaint?
Martin: I'd just as soon keep it just between the two of us.
Frasier: I see. Is this woman really so repulsive that you're willing to sacrifice all your nights just to avoid a date with her?
Martin: Well, let me put it this way: years of chewing tobacco have discolored her tooth. [laughs] Someone left a book of one-liners in the lost and found.
