So this guy goes into a pet store and sees a beautiful parrot but it has a blue string handing from one foot and a red one from the other. He thinks this is a little strange so he asks the shopkeeper what the strings are for.
"Well this is a highly trained parrot" the shopkeeper replies. "If you pull the red string he talks in French, if you pull the blue string he talks in English".
"Wow" exclaims the man shopping that's really neat "What happens if you pull them both at the same time?"
"I fall off my perch you idiot!" exclaims the parrot.
