A quiet, polite man owns a disgusting, foul mouthed parrot.
One day, it gets to be too much, so the man locks the bird in a kitchen cabinet. When the man finally lets him out, the bird cuts loose with a stream of vulgarities, so the man puts the bird into the freezer.
After a few seconds of clawing and thrashing, it suddenly gets VERY quiet.
The man opens the freezer door. The bird calmly climbs onto the man's outstretched arm and says, "I'm very sorry. I promise I'll never curse again."
The man is astonished. Then the parrot says, "By the way, what did the chicken do?"
