A blind man walks unwittingly into a Lesbian bar, sits down, orders a pint, and begins telling jokes. Nobody alerts him to his error, and an audience quickly forms, when he says. "I tell you, I have some good blonde jokes!". A young lady tells him, "since you cannot see, you should know, before you tell this joke, that the bar-maid is blonde, the woman on your left is a blonde policewoman, the woman opposite you is a blonde weight-lifter, the woman to your right is a blonde black belt in judo and both bouncers are also blonde. Are you sure that you want to tell this joke?". He thinks about it for a while, and says, "You're right. I couldn't stand explaining it six times."
