Penn and Teller are a famous American magician duo, consisting of Penn Jillette and Teller. They have been performing together since 1975 and are known for combining comedy with magic illusions. Penn Jillette is the talkative member who serves as the act's orator and raconteur, while Teller is mostly silent during performances, relying on mime and nonverbal communication. They have gained acclaim for their magic shows, including long- running performances in Las Vegas, and are also recognized for their advocacy of scientific skepticism and libertarianism. Their partnership has lasted over 50 years, beginning from their first meeting in 1975 and evolving through various stages of their career from street performances to Broadway and television shows like "Penn & Teller: Fool Us" and "Penn & Teller: Bullshit!"
