Penn & Teller: Fool Us is a magic competition television series in which magicians perform tricks in front of American magician-comedian duo Penn and Teller. The pilot of Fool Us was first commissioned by John Kaye Cooper, the controller of entertainment for ITV, in 2011. After each performance, the magician(s) who performed it win a Fool Us trophy (since season 2) and a five-star trip to Las Vegas to perform as the opening act in Penn's show. A backstage judge or judges, versed in the techniques of the magic industry and privately informed how the trick is done prior to the show, makes any necessary calls whether Penn or Teller were fooled.
