Niles: Well, this evening is an entire disaster. I'm already late for dinner with Maris. I just don't know how this could have happened. [walks to door but doesn't open it]
Frasier: Yes, who'd have guessed that something so innocent as spying on a man's girlfriend and rifling his underwear drawer can turn so ugly.
Niles: Well, there is one consolation. We told Dad the truth and we were able to bear his anger. That's the nice thing about our relationship. We're all adults. We can talk things through. We're not afraid of confrontation...
Frasier: Stop stalling, Niles. Dad must be on the elevator by now.
