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 a few things. Our bartender IS blonde, the bouncer is blonde. I'm 6'4", 230 lbs and a black belt. The guy sitting next to me is 6'7", weighs 270, and he's a professional linebacker. The fella to your right is 6'5" pushing 300 and he's a wrestler and professional weightlifter. Each one of US is blonde. Think about it, Mister. Do you still wanna tell that joke?"
The blind guy says, "Nah, not if I'm gonna have to explain it five times."
