Quote from Cliff in Little Carla, Happy at Last: Part 1
Cliff: Oh, hey, isn't that Eddie LeBec sashaying down those stairs, there, Doc? Frasier: Sure looks like it. Cliff: But Carla's here. Isn't there some superstition about the groom seeing the bride before the wedding? [Eddie screams as he walks into the bar and sees Carla, who screams when she sees him] Frasier: Nobody believes in that anymore.
