A tv repairman was called to a house one day. The woman of the house said to him, "I own a huge, vicious-looking dog but he will not harm you.But for God's sake do not speak to the parrot I own. Promise, okay?"
       The repairman assured her that he would follow her orders.
       Upon entering the house the repairman was not bothered by the dog but the parrot screamed vulgarities and insults continuously.
       "Oh, for heaven's sake," shouted the repairman,"Will you shut your filthy mouth!"
       To which the parrot screamed, Sic 'im, Bruno!"
