Mary received a parrot as a gift. The parrot was fully grown with a very bad attitude and worse vocabulary. Every other word was profanity; those that weren't profanity were, to say the least, rude.
Mary tried to change the bird's attitude by constantly saying polite words and playing soft music, anything she could think of. Nothing worked.
She yelled at the bird and the bird got worse. She shook the bird and the bird became even madder and ruder. Finally, in a moment of desperation, Mary put the parrot in the freezer to get a minute of peace.
For a few moments she heard the bird swearing, squawking, kicking and screaming. Then, suddenly, there was absolute quiet. Mary was frightened that she might have actually hurt the bird and quickly opened the freezer door.
The parrot calmly stepped out onto Mary's extended arm. Perfectly calm, the parrot said, "I am very sorry that I offended you with my language and my actions and I ask your forgiveness. I will endeavor to correct my behavior, and I am sure it will never happen again."
Mary 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?"
