Here are some cleverly complex interviews where Colbert takes on the skeptics. There is real tradecraft here—he confronts the skeptics boldly without humiliating them. Most of these guests show up for multiple appearances (he interviewed Richard Dawkins and Bart Ehrman twice, and Neil deGrasse Tyson nine times). Some of his quips poke fun at shallow arguments for the very epistemology Colbert seeks to support, while demonstrating an insightful appreciation for apologetic arguments and contemporary skepticism. As W.C. Fields once quipped, “Comedy is serious business.”
