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 lb. blonde with a black belt in karate.
What's more, the woman sitting next to me is blonde and she's a weight lifter. The lady to your right is a blonde, and she's a wrestler. Think about it seriously, Mister. You still wanna tell that joke?"
The blind guy says, "Nah, not if I'm gonna have to explain it five times."
