Mister Magic

The magician shows a card on which the picture of a wizard dressed in black can be seen. He takes this card behind his back for a second and then shows that the wizard has changed clothes "as quick as lightening" and is now dressed in red. Of course, if this had happened several times, the spectators presume that the card shows on the front side a wizard dressed in black, on the back side one dressed in red. The spectators will ask the magician to turn the card but suddenly, there is a wizard dressed in blue. If the card is turned once again, the spectators will be astonished to see a wizard sitting on the "WC".
