Frasier: Hello, Sam, old buddy.
Sam: Frasier. What the hell are you doing here? Are you alone?
Frasier: Yes, I'm alone. I didn't marry Diane.
Sam: You didn't?
Frasier: No, I didn't. Does that make you happy?
Sam: Well, I'm happy for you. Just how'd you manage that?
Frasier: Well, she left me at the altar. I had just vowed to take her for my wife. The priest asked her if she would marry me. She looked around and asked if he was talking to her. He nodded, and she was gone.
