Quote from Niles in Rivals
Niles: Roz, you didn't tell me Frasier was going to be here. Roz: Yeah, he bought the last two tickets. Niles: After he knew I'd be here with Poppy. Obviously he wants to get a shot at her himself, he bought that woman along as his beard. Roz: Do you think Frasier's interested in Poppy? Niles: I shouldn't be surprised the subtle signs of attraction are lost on you. A woman to whom the gunning of a Harley engine is like a come-hither look.
