Created by Upright Citizen Brigade (UCB) Theatre co-founder Matt Besser (Parks & Recreation, Reno 911!), improv4humans is one of the premier comedy podcasts and a flagship program of the Earwolf podcast network. The fully improvised weekly show features some of the best performers in the industry and the occasional movie star. Each week, Besser guides a new panel of comedians through various scenes based on random suggestions from the audience.
