Quote from Niles in Fool Me Once, Shame on You. Fool Me Twice...
Frasier: My car was stolen. Martin: You're kidding. Frasier: Yes, once again, I fell victim to a master criminal. Martin: How'd they do it? Hot-wire it? Boy, you know, those guys got fingers like concert pianists. Frasier: No. He had the key. Martin: Oh, a real pro, huh? He made a wax impression and then had a duplicate key made? Frasier: No. It was the same miscreant who stole my briefcase. He used the spare set that was inside. Martin: What? He tailed you for a few days, learned your routine, so he'd know where to find the car? Frasier: Not exactly. He called the station and we agreed to meet. Martin: What for? Niles: Low-fat lattes and biscotti.
