The blind man sits down, thinking he'd break the ice with the bartender by asking "Wanna hear a blond joke?"
In a hushed voice, a man beside him says "Before you tell that joke, you should know our bartender IS blonde, or bouncer is blond, I'm a 6'4" black belt, the man sitting on the other side of me is 6'2, 250lbs, and a rugby player. The guy sitting next to you is pushing 300, 6'6, and he's a wrestler. We're ALL blond. So you think about it mister, do you really wanna tell that joke?"
The blind man sat for a second, thinking over the odds and then replied "No, not if I have to explain it five times."
