Ventriloquist.

A young ventriloquist is touring the clubs and one night he's doing a
show here in Edmonton. With his dummy on his knee, he starts going
through his usual dumb blonde jokes when a blond woman in the 4th row
stands on her chair and starts shouting:
 I've heard enough of your stupid blonde jokes. What makes you think
you can stereotype women that way? What does the color of a person's
hair have to do with her worth as a human being? Its men like you who
keep women like me from being respected at work and in the community,
and from reaching our full potential as people. You and your kind
continue to perpetuate discrimination against not only blondes, but
women in general...and all in the name of humor!'

The  embarrassed ventriloquist begins to personally apologize, and
the blonde yells,

'You stay out of this! I'm talking to that little bastard on your lap!'
