Al: Well, I've invited her over for Friday night. Told her there would be a few people. Now I just have to find a few people. Would you and Jill like to come?
Tim: Can't make it. And if you were smart, you wouldn't show up either.
Al: Why?
Tim: Jill is the world's worst matchmaker. She put seven couples together. Six are getting divorced.
Al: Well, maybe we would be like the seventh couple.
Tim: The seventh couple couldn't get married. Turned out they were cousins.
