As a second here at work on this Sunday I could use some new and original scUM jokes

Two University of Michigan fans were walking down the street when they came upon a dog lying on the sidewalk licking and cleaning his groin like dogs do. The first University of Michigan fan says to the second, "Boy, I wish I could do that." The second University of Michigan fan replies, "Yeah, me too. But I wouldn't try it." The first University of Michigan fan asks, "Why not?" The second University of Michigan fan replies, "Because I'm afraid the dog might bite me."
