Well the joke goes like this.....a blind man is sitting at a bar and begins to tell the guy next to him a dumb blonde joke....The guy stops him and says: "Before you go any further. ...I have to warn you ...the bartender is blond....the bouncer is blond...the waitress is blond....and there's a blond cop on the other side of you......
So the blind man says: " Forget it then. ....it's not worth it if I'm going to have to explain it 4 times..."
