David received a parrot for his birthday. This parrot was fully-grown with a bad attitude and very rude.
David tried hard to change the bird's attitude and was constantly saying polite words, playing soft music, anything that came to mind. Nothing worked. He yelled at the bird, the bird got worse. He shook the bird and the bird got madder and ruder.
Finally, in a moment of desperation, David put the parrot in the freezer. For a few moments he heard the bird squawking, kicking and screaming and then, suddenly, all was quiet.
David was frightened that he might have actually hurt the bird and quickly opened the freezer door.
The parrot calmly stepped out onto David's arm and said: "I'm sorry that I offended you with my behavior and actions. I ask for your forgiveness. I will try to check my behavior..."
David was astounded at the bird's change in attitude and was about to ask what changed him when the parrot continued, "May I ask what exactly the chicken did?"
