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:
“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.”
