Penn & Teller are Las Vegas headliners whose act is an amalgam of illusion and comedy. Penn Jillette is a raconteur; Teller generally uses mime while performing, although his voice can occasionally be heard throughout their performance. They specialize in gory tricks, exposing quacks and frauds, performing clever pranks, and have become associated with Las Vegas, atheism, scientific skepticism, and libertarianism.



The duo will sometimes perform tricks that discuss the intellectual underpinnings of magic. One of their acts, titled "Magician vs. Juggler", features Teller performing card tricks while Penn juggles and delivers a monologue on the difference between the two; jugglers start as socially aware children who go outside and learn juggling with other children, magicians are misfits who stay in the house and teach themselves magic tricks out of spite.
