Highly Trained Parrot
A man goes into a pet shop and sees a beautiful parrot with a red string tied to its left leg and a green string tied to its right leg. "What are those strings for?", he asks the store owner. "This is a highly trained creature," the owner explains. "If you pull the red string, he speaks Spanish and if you pull the green string he speaks French."
"What happens if you pull both strings at the same time?" the man asks.
"I fall off my perch, you idiot!" squawks the parrot.
