A young man named John received a parrot as a gift. The parrot had a bad attitude and an even worse vocabulary. Every word out of the bird's mouth was rude, obnoxious and laced with profanity.
John tried and tried to change the bird's attitude by consistently saying only polite words, playing soft music and anything else he could think of to "clean up" the bird's vocabulary.
Finally, John was fed up and he yelled at the parrot. The parrot yelled back. John shook the parrot and the parrot got angrier and even ruder. John, in desperation, threw up his hand, grabbed the bird and put him in the freezer.
