A blind guy on a bar stool shouts to the bartender
"Hey! Wanna hear a blonde joke?"
The bar immediately becomes absolutely quiet. In a hushed voice, the guy next to him says, "Before you tell that joke, you should know something.
The BARTENDER is blond, the BOUNCER is blond and I'm a 6' tall, 200 lb blond with a black belt in karate.
"What's more, the guy sitting next to me is 6'2," weighs 225 lb and he's a blond weight lifter," he continues, "The fella to your right is blond, 6'5" and pushing 300 lb and he's a wrestler.
Think about it seriously, Mister. You still wanna tell that joke?"
The blind guy goes: "Nah! Not if I'm gonna have to explain it five times."
