There's a vicar who's given a parrot as a present. It's a talking bird, but the problem is every other word it says is a swearword. This is a big source of embarrassment for the vicar and he tries everything to get the parrot to stop swearing, but nothing works. One Sunday lunch time he finally loses it. He grabs the bird cage, opens up the freezer and shoves the parrot inside. He slams the door shut and there's a muffled stream of the most obscene words you can imagine. After a few minutes everything goes quiet. The vicar's calmed down a bit by now, and he doesn't want to harm the parrot, so he opens the freezer up and puts the bird back in its cage. The parrot looks at him in silence for a few moments, then it says "I believe I may have offended you with my language, and I am truly sorry". The vicar is amazed, and is about to question the bird's sudden change when the parrot continues "Can I just ask, what on earth did the chicken do?".
