Eight of Andy Richter's ten nearest neighbors by audience similarity — a measure of how closely two entities' audiences resemble each other in composition — are fellow comedians, and the scores compress into a narrow band from 0.97 down to 0.96, with no single standout pulling away from the rest.
Marc Maron (0.97) and Patton Oswalt (0.97) sit at the top, followed closely by Michael Ian Black (0.97), Mike Birbiglia (0.96), John Hodgman (0.96), Jemaine Clement (0.96), Conan O'Brien (0.96), and John Oliver (0.96). The two departures from that pattern are Last Week Tonight (TV Shows, 0.96) and Bob Odenkirk (Actors, 0.96) — both sitting within the same tight range rather than at any distance from the comedian cluster. The flat shape means no single neighbor dominates; the audience is drawn consistently across a cohesive group of comedy-adjacent figures rather than anchored to any one of them.
The overall picture is a tightly defined comedy audience with essentially no cross-category drift in the top 10 — the two non-comedian entries are adjacent enough in tone that they barely register as exceptions.
