A blind guy on a bar stool shouts to the bartender, "Wanna hear a blonde joke?"
In a hushed voice, the guy next to him says, "Before you tell that joke, you should know something. Our bartender is blond and the bouncer is blond. I'm a 6' tall, 200-pound black belt veteran of the Special Forces. The guy sitting next to me is 6' 2", weighs 225 and he's a rugby player. The fella to your right is 6' 5", pushing 300 pounds and he's a wrestler. Each one of us is blond. Think about it, mister. You still wanna tell that joke?"
The blind guy thinks for a moment and replies, "Nah, not if I'm going to have to explain it five times."
