Fool Us challenges magicians to perform in front of Penn and Teller. If they can fool Penn and Teller, they win a five star trip to Las Vegas to perform as the opening act in Penn & Teller's world famous show at the Rio Hotel & Casino. Las Vegas legends Penn & Teller have no prior knowledge of either the performers or the planned trick. They sit in the audience just like everyone else, watching every move the guest magicians make. And, if any illusionist comes on and fools the professionals - they win a five star trip to Las Vegas to perform as the opening act in Penn & Teller's world famous show at the Rio Hotel & Casino.
