A parrot was in a pet shop with a string attached to each leg when a man walked in looking to buy a pet. A shopkeeper came over and started to try and sell him a dog when the man noticed the parrot.

He asked what the strings were for and the shopkeeper replied, "Well, if you pull the right string the parrot says, 'Polly wanna cracker'.

If you pull the left string it says, 'my name's Sam' ".

The man being of the inquisitive nature tried both and thought it was really neat, but was still curious. So he asked what would happen if he pulled both strings, the parrot piped up . . . .

. . . "I'd fall off the perch you idiot!!!"
