WHO THEY ARE
Penn & Teller (Penn Jillette and Teller) are American magicians and entertainers who have performed together since the late 1970s, noted for their ongoing act that combines elements of comedy with magic. The duo has been featured in numerous stage and television shows such as Penn & Teller: Fool Us, and they currently perform in Las Vegas at The Rio, the longest running headlining act in Las Vegas history. Penn Jillette serves as the act's orator and raconteur. Teller generally does not speak while performing, and instead communicates through mime and nonverbals, though his voice can occasionally be heard during their live shows and television appearances. Besides magic, the pair has become associated with the advocacy of scientific skepticism, and libertarianism, particularly through their television show Penn & Teller: Bullshit!.
Jillette has told interviewer Larry King and Seth Meyers that a big part of the duo's success and longevity is due to their never having been close friends. They respect each other as business partners and enjoy working together, but have little in common besides magic. As a result of their drastically different lifestyles and interests, they rarely socialize or interact when not working.
However, Jillette has also said, in a video where he and Teller responded to questions from members of Reddit and also in a video interview for Big Think, that while they share few interests outside magic, Teller is his best friend and his children treat him as a close relative. He stated that while most entertainment partnerships such as Martin and Lewis and Lennon–McCartney were based on a deep affection for each other that lends to a certain volatility when things go wrong, their business relationship and friendship is based on a respect for each other. Teller has made similar statements. In an NPR interview, Teller said their disagreements often lead to better artistic decisions because they bring out new ideas and expand the range of discussion
