The Dummy and the Blonde
A Ventriloquist with his dummy on a knee starts his act. One bit requires his dummy to tell Dumb-Blonde Jokes.
After a few jokes, an angry blonde woman finally stands up and starts speaking her mind. "I have had it with the stereotyping of all blondes being stupid!" the woman yells, and she continues ranting on about this.
Finally, the ventriloquist says, "Sorry ma'am ..."
The woman cuts him off by saying, "You stay out of this. I'm talkin' to the dummy."
