Wilma: Fred, I wanna thank you for being so nice to Mother.
Fred: I'm tryin', Wilma, I'm tryin' hard.
Wilma: I know, dear, and I think you're winning her over.
Fred: I sure hope so.

Wilma's Mother: Why don't you look where you goin', Clumsy?
Fred: I'm sorry, mother-in-law dear, I didn't expect you to stick your foot out. (mumbles) I love my mother-in-law. I love my mother-in-law.
