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