Here's one....
A young ventriloquist is touring the clubs and stops to entertain
at a bar in a small town.
He's going through his usual run of stupid blonde jokes, when a
large, blonde woman in the fourth row stands on her chair and says,
"I've heard just about enough of your denigrating blond jokes! What
makes you think you can stereotype women that way? What does a
person's physical attributes have to do with their worth as a human
being?"
The ventriloquist looks on in amazement.
"It's guys like you who keep women like me from being respected at
work and in my community," she continued, "and of reaching my full
potential as a person because you and your kind continue to
perpetuate discrimination against not only blondes but women at
large... all in the name of humor."
Flustered, the ventriloquist begins to apologize.
The blonde interjects, "You stay out of this, mister, I'm talking
to that little bastard on your knee!"
