There was once a man with a parrot. He was the conservative, religious type, and the trouble was that his parrot had the foulest mouth you ever did hear! It could swear for five minutes on end without repeating himself.
One day the man could stand the bird's profanity no longer and he grabs the bird by the throat and shouts "Quit it! I can't stand it any more!"
This just provokes the parrot and he swears even more. Furious, the man locks the parrot in the kitchen cupboard, but the parrot's constant clawing, scratching and squarking just drives the guy crazy so he lets it out.
The parrot lets out a stream od obscenities that would make even an old sea-dog blush.
More irate than ever, he flings the foul-mouthed parrot into the freezer and slams the door. The parrot bangs and swears and stamps about, but suddenly it falls silent inside the freezer. Worried that the parrot may have hurt himself, the man opens the door and to his amazement the parrot climbs placidly onto the man's outstretched arm and says, "Awfully sorry about the trouble I gave you. I'll try to improve my language from now on." The man is astounded! "By the way", says the parrot, "what did the chicken do?"
