The comedian Paul Scheer has had roles on some of the biggest sitcoms ever, including “30 Rock,” “Parks and Recreation” and “The League.” He also co-hosts one of the most popular podcasts in the world, “How Did This Get Made,” which takes on the worst movies of all time. But in his new memoir, “Joyful Recollections of Trauma,” Paul writes about the abuse he and his mom suffered at the hands of his stepfather. He joins Tom to share how he escaped the cycle of abuse, why pain often leads to humour, and how he found a community in improv comedy.
