The Supercar Registry

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 a 'Billy-club'.
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."
