Blind Man's Blonde Joke

A blind man enters a lesbian bar by mistake. He finds his way to a bar stool and orders a drink.
After sitting there for a while, he yells to the bartender in a loud voice, "Hey bartender, you wanna hear a dumb blonde joke?"!!!
The bar immediately falls deathly quiet. In a very deep, husky voice, the woman next to him says, "Before you tell that joke, sir,
I think it is just fair, given that you are blind, that you should know five things...
1 - The bartender is a blonde woman. 2 - The bouncer is a blonde woman. 3 - The woman sitting next to me is blonde and is a professional weightlifter. 4 - The lady to your right is a blonde and is a professional wrestler, and 5 - I'm a 6 foot, 200 lb. blonde woman with a PhD., a black belt in karate and a very bad attitude!
Now think about it seriously, Mister.
Do you still want to tell that joke?"
The blind man thinks for a second, shakes his head, and says; "Naaaah . . . not if I'm gonna have to explain it five times."
