A blind man and his guide dog enter a bar and find their way to a barstool. After ordering a drink, and sitting there for a while, the blind guy yells to the bartender, "Hey, you wanna hear a blonde joke?"

The bar immediately becomes absolutely quiet.

In a husky, deep 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's a weightlifter. The lady to your right is a blonde, and she's a pro wrestler. Think about it seriously, mister. You still wanna tell that blonde joke?"

The blind guy says, "Nah, not if I'm gonna have to explain it five times."
