A magician doesn't become a master by fooling his audience. A magician becomes a master by fooling other magicians. Dallas magician Zak Mirz did just that to two of the world's most knowledgeable magicians. Mirz appeared on The CW magic series Penn & Teller: Fool Us in which the famed Las Vegas magic duo watch original magic tricks performed by illusionists from every corner of the world. Then they try to figure out how the trick is done using Teller's storied knowledge of magic secrets and techniques and Penn's booming voice and expressive vocabulary without revealing how the trick is done to those who don't know the lingo. Mirz, a native of Iran who used magic from a very young age to cope with the tragic loss of his father, performed a card trick with host Alyson Hannigan using a deck of cards and a very sharp knife that she used to cut to the predicted card. Penn & Teller thought they had the trick figured out, but Mirz told them they were wrong, earning him two dropped jaws of shock, a cloud of stage confetti and the show's fabled "Fool Us" trophy with the "F" and "U" in big, red capital letters.
