There is a blind man in a bar, sitting on a stool drinking and he has had quite a few beers already.
He shouts out to the bartender, “Hey, you wanna hear a blonde joke?”
In a hushed voice, the guy sitting next to him says, “Excuse me, but before you tell that joke, you should know something. Our bartender is blonde and the bouncer is blonde. I’m a 6′ tall, 200lb black belt veteran of the Special Forces. The guy sitting next to me is 6′ 2″, weighs 225lbs and he’s a rugby player. The fella to your right is 6′ 5″, pushing 300lbs and he’s a wrestler. Each one of us is blonde. Think about it, mister. You still wanna tell that joke?”
The blind man thinks for a moment and replies, “Nah, not if I’m going to have to explain it five times.”
