Bob Brunner heard this one and passed it on to us.
When the repairman arrived at Mrs. Shoemaker's apartment the next day, he discovered the biggest and meanest looking Doberman he had ever seen. But, just as she had said, the dog just lay there on the carpet watching the repairman go about his business. However, the whole time he was there, the parrot drove him nuts with his incessant yelling, cursing, and name calling.
Finally, the repairman couldn't contain himself any longer and yelled, "Shut up, you stupid, ugly bird!"
To which the parrot replied, "Get him, Spike!"
