Swearing Parrot.

So there's this fella with a parrot. And this parrot swears like a
sailor, I mean he's a pistol. He can swear for five minutes straight
without repeating himself. Trouble is, the guy who owns him is a quiet,
conservative type, and this bird's foul mouth is driving him crazy.  One
day, it gets to be too much, so the guy grabs the bird by the throat,
shakes him really hard, and yells, 

"QUIT IT!"  

But this just makes the bird mad and he swears more than ever.  Then the 
guy gets mad and says,

"OK for you." 

and locks the bird in a kitchen cabinet. This really aggravates the bird 
and he claws and scratches, and when the guy finally lets him out, the 
bird cuts loose with a stream of vulgarities that would make a veteran 
sailor blush.

At that point, the guy is so mad that he throws the bird into the
freezer. For the first few seconds there is a terrible din. The bird
kicks and claws and thrashes. Then it suddenly gets _very_ quiet.  At
first the guy just waits, but then he starts to think that the bird may
be hurt. After a couple of minutes of silence, he's so worried that he
opens up the freezer door.

The bird calmly climbs onto the man's outstretched arm and says,

"Awfully sorry about the trouble I gave you. I'll do my best to improve
my vocabulary from now on."

The man is astounded. He can't understand the transformation that has
come over the parrot. Then the parrot says, 

"By the way, what did the chicken do?"
