A ventriloquist is performing with his dummy on his lap. He’s telling a dumb-blonde joke when a young platinum-haired beauty jumps to her feet. “What gives you the right to stereotype blondes that way?” she demands. “What does hair colour have to do with my worth as a human being?”

Flustered, the ventriloquist begins to stammer out an apology.

“You keep out of this!” she yells. “I’m talking to that little jerk on your knee!”
