This guy goes to a pet shop to buy a parrot. There he sees a parrot with a red string tied to its left leg and a green string tied to it’s right leg. He asks the owner the significance of the strings.

“Well, this is a highly trained parrot. If you pull the red string he speaks French; if you pull the green string he speaks German,” replies the shop keeper.

“And what happens if I pull both the strings?” our curious shopper inquires.

“I fall off my perch you fool!!” screeches the parrot.
