Alan gets married and divorced a second time to the very young and attractive, Kandi. He's lovable and annoying at the same time.
Charlie: For every gorgeous woman out there's a guy tired of banging her.
Alan: But that guy is never me.
Alan: Oh, Judith, when did you start hating me so much?
Judith: Well, let's see: I disliked you when we were married, I resented you when we divorced, but I don't think I hated you until you started having sex with that gorgeous 22 year-old dumbbell.
Alan: OK, well, thanks for clearing that up
