An old, blind cowboy  wanders into an all-girl biker bar by mistake. He finds his way to a bar stool and orders a shot of Jack Daniels.

After sitting there for a while, he yells to the bartender, '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:

1. The bartender is a blonde girl with a baseball bat.

2. The bouncer is a blonde girl with spurs on her boots..

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 weight lifter.

5. The lady to your right is blonde and a professional wrestler.

Now, think about it seriously, Cowboy. Do you still wanna tell that blonde 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.'
