A man and his wife walk into a pet store and see a parrot in a cage. The man walks over, and the parrot says, "Hey buddie, your wife sure is ugly."
The man storms over to the owner and says, "Do you know what your parrot said to me," and proceeds to tell the owner.
The owner goes over to the parrot, jerks him out of the cage, slaps him around, and tells him, "You know what I told you about that, this is your last chance!" He puts the parrot back into the cage.
The man and his wife go back by the parrot's cage on their way out of the store and the parrot says, "Hey buddie" while looking back and forth between the man and the owner.
The man says, "What?"
The parrot says, "You know what."
