An old, blind cowboy wanders into an all-girl biker bar by mistake. He finds his way to a bar stool and orders a beer.
After sitting there for a while, he yells to the bartender, "Hey, you wanna hear a blonde joke?"
The bar immediately falls deathly silent. In a very deep, husky voice, the woman next to him says: "Before you tell that joke Cowboy - given that you are blind and all, I'm gonna cut you some slack and tell you five things:
1. The bartender is a blonde girl with a baseball bat.
2. The lady guarding the front door is a blonde.
3. I'm a 6-foot tall, 175-pound blonde woman with a black belt in karate.
4. The woman sitting next to me is blonde and a professional weightlifter.
5. The lady to your right is blonde and a champion wrestler.
'Now that you know - think about it seriously, Mister. Do you still wanna tell that joke?'
With this the blind cowboy thinks for a second, shakes his head, and mutters:
"Hell no...not if I'm gonna have to explain it five times....."
