Jon & Hank's Stupid Card Trick

A deck of cards is shown to be normal (red backed) on the backs and to be al Jokers on the face. A spectator is asked to point a red backed joker as you fan the cards face up before the spectator. This is the stupid part! Ask the spectator to turn the card over.

Its is indeed a red backed Joker! Still pretty stupid! The performer turns over the deck and fans the cards. The rest of the deck is now shown to consist of blank backed Jokers! The red backs have all vanished.
