Well-Endowed Hunchback

A guy is at a urinal in a public restroom when a hunchback walks in and stands next to him. He glances over and sees that the hunchback has a gigantic penis.

The guy says, "Man, if I had a d**k that big, I would be sucking it all day."

The hunchback replies, "How do you think I got to be a hunchback?"
