This guy gets a parrot but it's got a bad attitude and foul vocabulary. He tries everything to change the bird's attitude and clean up its talk but nothing works.
Finally, in a moment of desperation, he puts the parrot in the freezer. For a few moments he hears the bird squawking, kicking and screaming and then, suddenly, all is quiet. He opens the freezer door. The parrot steps out and says, "I'm sorry that I offended you with my language and actions. I ask for your forgiveness.
The guy's astounded at the bird's change in attitude and was about to ask what changed him when the parrot continued, "By the way, may I ask - what did the chicken do?"
What did the inflatable teacher say to the inflatable boy who turned up at the inflatable school with a hedgehog?"You've let me down, you've let the school down and you've let yourself down!!"
