In theory, Mobituaries is a show about people and things that are lost to the past—hence the “obituaries” pun. In practice, it’s a celebration of the pop culture and folklore that drive the host Mo Rocca’s imagination, filtered through blunt-force nerd humor that will win over any listener. One riveting episode analyzes how various sitcoms have handled the process of writing off characters; in another, Rocca tries to get a man who poisoned two majestic oaks in the name of a college football rivalry to make amends. Nothing captures the ethos of the show quite like “Billy Carter: Death of the First Brother,” which resurrects the story of President Jimmy Carter’s younger brother—part cowboy, part poet, part drunk, now mostly forgotten. In 2019, Mobituaries showcased an unparalleled sense of wonder, spinning nostalgia into character-driven stories that are unsentimental love letters to Rocca’s obsessions.
