A blind man walks into a bar.

He hears a man speaking next to him. So he says, "Hey do you want to hear a blonde joke?"
The man says, " Sir, I myself am blonde and weigh 250 pounds, the bartender is also blonde and is well built, and there are a couple of blonde men seated at the table behind us and look like the type you wouldn't want to mess with. Do you still want to tell the joke?"
The blind man says, "No that's fine. I don't want to explain the joke so many times."
