Comedian-Magicians Penn & Teller, play in the Penn & Teller Theatre at the Rio. Penn is over six feet tall and talks a blue streak. His partner, Teller, is much shorter and never speaks during the performance. But they are both excellent magicians. They even do an explanation of "cold reading" as done by psychics such as John Edwards. They strip away the trappings of the tricks and still manage to baffle the audience as to how they are done.
After the show, they both run down the aisle to the lobby, where they patiently sign autographs and pose for pictures with their fans. They do this until every guest has filed by.
