He is an atheist, debunker, skeptic, and a fellow of the Cato Institute (a free market libertarian think tank that also lists Jillette as a fellow), an organization which is featured prominently in the duo's Showtime series Bullshit!.
Teller legally changed his name from "Raymond Joseph Teller" to the mononym "Teller".
