Quote from Roz in Mary Christmas
Frasier: You see, Kelly's looking for a new co-host for the parade this year and I was hoping it might be me. You know, I've watched that parade since I was a child and this is my chance to become a part of it. Roz: Oh, I thought she did that parade with her husband. Frasier: Oh, I guess you haven't heard. You see, she's discovered that Cal's been having an affair with her cue card girl. Roz: How did she catch him? She find a giant love letter in his pocket?
