An old, blind cowboy wanders into an all-girl biker bar by mistake. He finds his way to a bar stool and orders some coffee. After sitting there for a while, he yells to the waiter, "Hey, you wanna hear a blonde joke?"
The bar immediately falls absolutely silent. In a very deep, husky voice, the woman next to him says, "Before you tell that joke, Cowboy, I think it is only fair, given that you are blind, that you should know five things. The bartender is a blonde girl with a baseball bat, the bouncer is a blonde girl, I'm a 6-foot tall, 175-pound blonde woman with a black belt in karate, the woman sitting next to me is blonde and a professional weightlifter, and the lady to your right is blonde and a professional wrestler. Now think about it seriously Mister. Do you still wanna tell that joke?"
The blind cowboy thinks for a second, shakes his head, and mutters, ‘"No, not if I'm gonna have to explain it five times."
