Blonde and the Ventriloquist

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 big blonde woman in the fourth row stands on her chair and says: "I've heard just about enough of your denigrating blonde jokes, Asshole. 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? It's guys like you who keep women like me from being respected at work and in my community, 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, when the blonde pipes up, "You stay out of this. Mister, I'm talking to that little bastard on your knee!"
