Quote from Martin in The Two Mrs. Cranes
Martin: What's going on here? Frasier: Clive is Daphne's old boyfriend. She's trying to let him down easily, by pretending to be married to Niles. Niles: So this is my place and Frasier's staying here temporarily because he's separated from Maris. Martin: [to Frasier] You couldn't stand her either, huh?
