Penn and Teller were introduced to each other by Wier Chrisemer, and they performed their first show together at the Minnesota Renaissance Festival on August 19, 1975. Besides magic, the pair has become associated with the advocacy of scientific skepticism and libertarianism, particularly through their television show Penn & Teller: Bullshit!. 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. Penn Jillette serves as the act's orator and raconteur. The duo has been featured in numerous stage and television shows such as Penn & Teller: Fool Us and currently perform in Las Vegas at The Rio, the longest-running headliners to play at the same hotel in Las Vegas history.
They are noted for their ongoing act that combines elements of comedy with magic. Penn & Teller, Penn Jillette and Teller, are American magicians, entertainers, and scientific skeptics who have performed together since the late 1970s.
