A man went to a pet shop looking to buy a parrot. The shop had several parrots but one was priced much lower than the others. When the man asked why one was so much cheaper than the others, the pet shop owner assured the man that he did not want the cheaper one because it had a very foul mouth.
"I've tried everything, but I can't get him to stop cussing", he explained.
Eager to save some money, the man bought the parrot, sure he could teach the bird not to cuss. He too tried everything to stop the parrot's foul mouth.
Finally, in frustration, he put the bird in the freezer to cool off. After a few minutes, he opened the freezer to find the parrot with a totally changed attitude.
"Please, I'll NEVER cuss again! Please let me out! By the way, what did the chicken do?"
