Though they came to fame as magicians Penn & Teller have turned their comedic talents to TV with PENN & TELLER: B*******! The duo debunks various popularly held ideas using Penn s acerbic wit (Teller is famously silent) and interviews with experts. With humor intelligence and a refreshing lack of tact the fourth season covers such touchy topics as abstinence capital punishment and Ground Zero. Since Showtime is its broadcast home Penn & Teller are free to curse and cover controversial topics with abandon in this Emmy-nominated series.
