There was a blind man in a bar, sitting on a stool drinking and he had clearly had quite a few beers already.
He shouted out to the bartender, “Hey, you wanna hear a blonde joke?”
In a hushed voice, the guy sitting on the bar stool next to him said, “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 thought for a moment and replied, “Nah, not if I’m going to have to explain it five times”.
