[Martin greets Frasier the morning after he slept with Roz]
Martin: You see the paper yet?
Frasier: Uh, no, I haven't.
Martin: Big story about how Roz's purse spent the night on the coffee table.
Frasier: [on Roz] You know what she's going to see when she looks at me now?
Martin: Your naked body.
Frasier: Oh, dear God! I was going to say, "somebody that's betrayed her trust," but oh, dear God!
Martin: [smugly] How come you can fly to Hawaii, but you can't fly to England?
Gertrude Moon: How come you can drive your car, but you can't do your own laundry?
Martin: [biting his tongue] Have a good trip.
[Later, when Frasier, Niles, and Martin are driving home]
Martin: "I can't do my own laundry because I can't carry the laundry basket AND my cane at the same time." That's what I should have said!
[to a bartender, looking for Daphne's father]
Dr. Niles Crane: Excuse me. Do you know a man named Harry Moon? And no, that is not the start of a limerick.
