Frasier: Niles! "Executive Match" is an escort service. One of Donny's clients was caught using them.
Niles: I don't believe you.
Frasier: Niles, does Sabrina laugh at everything you say? Is she fascinated by everything about you? Even your collections?
Niles: Well, yes. Actually, I even showed her my rarely-seen collection of eighteenth century Portuguese bud vases.
Frasier: And how did she react?
Niles: Well, if you must know, she was rather aroused. She said she loved a man who collected porcelain and-Oh, my God, I'm dating a whore!
