A friend gave George a parrot which had a big vocabulary, but most of the words the bird knew were bad words. At first George thought it was funny, but when George had important guests, the bird’s bad words embarrassed him very much.
    As soon as the guests left, George angrily shouted to the parrot, "That language must stop!" But the bird answered him with curses. He shook the bird and shouted again, "Don’t use those ugly words!" Again the bird cursed him.
    George was really angry. He took the parrot and threw him into the freezer. This time there was silence. After two minutes, George opened the door and removed the very cold parrot. Slowly the frightened parrot walked up George’s arm, sat on his shoulder and spoke into his ear, "I’m sorry for my behavior and will never behave badly again."
    George asked, "Why the change?" The bird answered, "Because I saw what you did to the other birds. What did the chicken say?"
