A blind man goes into a tavern, finds the bar, and sits down.
When the bartender comes over and asks what he'd like to
drink, he says, "I'd like to get a beer and tell blonde joke."
The bartender says, "Well, I'll give you a beer, no problem,
but you should know that I weigh 250 pounds, and I'm a
blonde. Also, my brother is sitting next to you.
He's also
about 250, and he's blonde too. My cousin is sitting at
the table behind you, he weighs almost 300 pounds, and
he's a blonde. Are you sure you want to tell the blonde joke?"
The blind guy thinks a minute, then says, "Well, I guess I'll
have the beer, but I won't tell the blonde joke."
"Why not?" asks the bartender.
"Well," the blind guy says, "I don't want to have to explain it
three times."
