A blind man and his guide dog enter a bar and find their way to a barstool. After ordering a drink, they sit for a while, then the blind guy yells to the bartender, "Hey, you want to hear a blonde joke?"
The bar gets real quiet. In a husky voice, the woman next to him says, "Before you tell that joke, you should know something. The bartender is blonde, the bouncer is blonde and I'm a 6' tall, 200 pound, blonde with a black belt in karate. What's more, the woman sitting next to me is blonde and she is a weight lifter. The woman to your right is a blonde, and she's a pro wrestler. Think about is seriously, Mister. You still want to tell that joke?"
The blind guy says, "Nah, not if I'm going to have to explain it 5 times."
