Penn & Teller
|This might be|
|But we're not sure|
Penn Jillette (born 1955) and Teller (born Raymond Joseph Teller in 1948) are a pair of professional magicians. For the uninitiated, Penn is "the big one with the long hair who talks", and Teller is "the short one who doesn't talk". As a general rule, Teller only speaks when he's not in character or when he can't be seen talking (e.g. outside the camera or when behind a puppet).
Outside of their longtime Las Vegas stage show, they are best known for their Showtime series Penn & Teller: Bullshit! in which they investigate and debunk topics of interest. Well, kind of… Penn & Teller are more than happy to take New Age trinkets, Feng Shui, and so on, but a number of episodes are "bullshit" themselves, especially those relating to politics, economics, and environmentalism. This has made them controversial figures in the skeptic community.
Their newer shows, Penn & Teller Tell a Lie (2011) and Penn & Teller: Fool Us (2011-2015) are not based on scepticism.
 Penn & Teller: Bullshit!
Penn & Teller: Bullshit! was a TV infotainment show in which a wide range of topics were investigated and debunked.
Unfortunately a number of episodes are bullshit themselves and veer off into pseudoscepticism and denialism. Generally speaking, the show's coverage of woo and general crankery is pretty good, while episodes that deal with social trends, politics, environmentalism, and economics vary in quality—in no small part due to the pretty strong libertarian beliefs of Penn & Teller. They usually acknowledge their own bias, and planned to end the show with a Bullshit episode on their own bullshit.
