The History of Fun is a three-voice history show about where holiday customs come from, and it runs on a simple arrangement. Russ Frushtick opens each episode, brings in Allegra Frank and Chris Plante, and hands the floor to whoever is that day's 'expert'. That person is expected to lead with an elevator pitch. Chris's pitch for 'The War on Christmas: A Brief History' is 'Puritans. Love them. Bill O'Reilly.' For 'Krampus, the Anti-Santa: A Brief History' he skips the pitch, promises to defend the fun of his topic, and gets reminded that he skipped it last time too. What follows is research read aloud, not narration. Sources get named along the way: a wiki entry on a federal court case, a New York Times blog, a quoted passage linking Krampus's birch branches and chains to possible initiation rites. Nobody else stays quiet for long. When Allegra traces the phrase Black Friday, a challenge over whether an early use was really the first ends in 'You may be right.' The same stretch covers the 'black' label as a sign of a very bad day and people skipping work on the Friday after Thanksgiving. The War on Christmas episode explains the Establishment Clause with a shrug about legal stuff getting complicated, then gets to a judge's ruling that Christmas had become largely secularized. The three connect that ruling to their own earlier point that the holiday was secular almost from the start. 'The Yule Lads & Yule Cat of Iceland: A Brief History' shows the table at its loosest. A cat said to eat anyone not given new clothes on Christmas Eve draws a comparison to a cruel cat-lady stereotype, a sudden thought about Dobby, and a hopeful theory that the legend pushed people to clothe the poor. That theory gets waved off in favor of a surprisingly capitalist origin tied to Iceland's sheep. 'Presidential Turkey Pardon: A Brief History' detours through 1947, when Truman's administration asked people to observe meatless Tuesdays and poultry-less Thursdays to save grain for Europe after the war. By the show's own account, that was not really a turkey pardon as the ritual is understood today. It does come with a newspaper pamphlet of meatless recipes, one involving canned salmon and crushed potato chips, and the episode closes by asking listeners for recipes. The mood is loose and self-mocking: a sore throat gets a zinc tip from a mock doctor of fun, and a Krampus aside turns into a joke about an Incubus song the show has no rights to play. The recurring sign-off is 'leap the dips'.
