The comedy magic duo known as Penn & Teller first met in 1974, when they were introduced by a mutual friend, Weir Chrisimer. The trio performed magic and comedy as the Asparagus Valley Cultural Society from 1975 to 1981.
In 1985, Penn & Teller, working as a duo, began an off-Broadway show, followed by a Broadway show that brought them frequent guest spots on "Late Night With David Letterman" and "Saturday Night Live."
Frequent touring, TV specials and a feature film, "Penn & Teller Get Killed," led to the pair starting a series of Las Vegas shows beginning in 1993. They performed at Bally’s and the MGM Grand before finding a permanent home at the Rio, where they christened the Penn and Teller Theatre in 2001.
The duo have hosted a variety of TV series, including an eight-season Showtime show, which took a skeptical eye to a variety of topics, including alternative medicine and alien abduction. Their most recent series, "Penn & Teller Tell a Lie" aired on the Discovery Channel in 2011.
Though they’ve enjoyed a working relationship of close to 40 years, Penn & Teller have vastly different personalities and are quite open about how little time they spend together outside of their nightly show. Penn, the outspoken half, has written books, including "Every Day Is an Atheist Holiday," appeared on reality shows such as "Celebrity Apprentice" and lent his voice to various venues, including as the announcer for Comedy Central for several years. Teller, who never speaks on stage, has also written books and a play, "Play Dead," which ran off-Broadway.
