"I wouldn't.. he'll bite."

I gotta tell you this funny joke I heard while away w/ my family in Tennessee. By the way, they're moving here next week. Can't wait!!!!
Anyway, the story goes likes this: Two old men are sitting on a front porch. There's an old dog laying next to them. Before long, the ol' dog starts licking himself. Old man #1 says to old man #1; "I sure wish I could do that."
Old man #2 says to old man #1; "I wouldn't.. he'll bite."
