A blind man enters a ladies bar by mistake. He finds his way to the bar stool and orders a drink. After sitting there for a while, he yells to the bartender, "Hey, you wanna hear a blonde joke?"
The bar immediately falls absolutely quiet. In a very deep, husky voice, the woman next to him says "Before you tell that joke sir, I think it is only fair - given that you are blind - that you know five things:
1/ The bartender is a blonde girl.
2/ The bouncer is a blonde girl.
3/ I'm a six foot tall, 100kg blonde woman with a black belt in karate.
4/ The woman sitting next to me is blonde and a professional weightlifter.
5/ And the lady to your right is a blonde and is a professional wrestler.
Now think about it seriously, mister - do you still wanna tell that joke?"
The blind man thinks for a second, shakes his head, and declares: "Nah, not if I'm gonna have to explain it 5 times."
