A blind guy on a bar stool shouts to the bartender "Hey! Wanna hear a blonde 
joke?"  The bar immediately becomes totally 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 says:  "Nah! Not if I'm gonna have to explain it five times."
