Penn and Teller
Penn & Teller are are a performing duo of magicians currently based out of Las Vegas. Penn Jillette is the taller of the two and does all of the talking during their acts and shows, Raymond Teller is almost always completely silent and does the bulk of the on stage conjuring. In addition to their stage show Penn & Teller made several movies in the 80's and 90's and have had multiple television appearances together. They also star in their own television show "Bull****" which focuses on debunking myths and espousing their personal brand of libertarian atheist politics. Teller speaks freely outside of the confines of the act. The pair have appeared on The West Wing, on which they appeared to make an American flag, wrapped in a copy of the Bill of Rights, disappear in a puff of flame and smoke.
From a conservative perspective, Penn and Teller can be both loved and hated. They have mocked things like religion, the war on drugs, the death penalty, warrantless wiretaps, illegal immigration opposition and circumcision, but also debunked aspects of environmentalism, 9/11 conspiracy theories, and gun control on their show Penn & Teller's Bull****, on Showtime. The duo are both atheists, and both have libertarian political views. Penn has verbally announced on their show that they do not at all agree with American conservatives.
