a ventriloquist is on stage doing his act with his dummy on his knee.
he starts going through his usual dumb blonde jokes when a blonde shouts,
"i've heard enough of your stupid blonde jokes."
"what does the colour of a persons hair have to do with their worth as a human being?"
"it's men like you, who keep women like me from being respected!"
the red faced ventriloquist begins to apologise, but the blonde shouts, "you stay out of this mate, i'm talking to that little fucker on your knee!"
