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 blonde, the bouncer is blonde. I'm a 6' tall, 200 lb black belt. 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 and he's a wrestler. 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"
