A blind man walks into a bar and sits next to a man with blonde hair. The blind man leans over and asks the man if he wants to hear a blonde joke. The man replies "Look, pal, the guy to your left is a 250lb bodybuilder. He's a blonde. The guy behind you is a golden gloves boxer that happens to be a blonde. The bartender has a shotgun under the bar and is a blonde. I'm in a biker gang and am a blonde. Are you sure you want to tell that joke?"
The blind man scrunches his face and leans away. He gets up and says "Nah, I wouldn't want to have to explain the joke four times."
