A blind man walks into a bar, taps the man next him, and says, "Hey, wanna hear a blond joke?"
The man says back to the blind man, "Look buddy, I'm blond. The man behind me is a 400-pound professional wrestler and he is blond. The bouncer is blond. The man sitting over to your left is also blond. Still wanna tell that blond joke?"
The blind man is silent for a moment and then says, "Nah, I wouldn't want to have to explain it five times."
