Jimmy received a parrot for Christmas.  The parrot was fully grown, with a very bad attitude and worse vocabulary. Every other word was an expletive; those that weren't expletives were, to say the least, rude.  Jimmy tried to change the bird's attitude by constantly saying polite words, playing soft music...  anything he could think of.

Nothing worked.

He yelled at the bird, and the bird got worse.  He shook the bird, and the bird got madder and more rude.

Finally, in a moment of desperation, Jimmy put the parrot in the freezer.

For a few moments he heard the bird swearing, squawking, kicking and screaming and then, suddenly, there was absolute quiet.

Jimmy was frightened that he might have actually hurt the bird, and quickly opened the freezer door.

The parrot calmly stepped out onto Jimmy's extended arm and said, "I'm sorry that I offended you with my language and my actions, and I ask your forgiveness.  I will endeavor to correct my behavior".

Jimmy was astounded at the changes in the bird's attitude and was about to ask what had changed him, when the parrot continued, "May I ask what the Chicken did?"
