Larry the cable guy did this joke. I don't have it word for word--but you'll get the just of it!
He talks about buying edible underware for his 400 pound girlfriend. Half way throught consuming (he says) "I started feeling nauseated, sweaty and light headed. You've heard of herpes, she gave me diabetes!!"
I don't think I have ever laughed so hard at a joke in my life. A little crazy nurse humor in me I guess.
