A blind guy sitting on a bar stool shouts to the bartender, " Wanna hear a blond joke?"
In a hushed voice, the guy next to him says "Before you tell that joke, you should know something:
Out Bartender is blonde, the bouncer is blond, I'm a 6' tall blackbelt. The guy sitting next to me is 6'2" weighs 225 lbs, and he's a rugby player. The fella to your right is 6'5" pushing 300 lbs and he's a wrestler. Each one of us is blonde. Think about it, Mister. Do you still wanna tell that joke?"
The blind guys says, "Nah, not if i'm gonna have to explain it 5 times!"
