In 1935, a diver searching Lake Champlain found something extraordinary: a nearly intact warship from the American Revolution. It was the Gunboat Philadelphia. In this episode, we dive into the story of how a ragtag American army built a fleet of ships to stand up against the British Navy in 1776 ... and lost. But that loss changed the course of U.S. history. So, how did Benedict Arnold and a bunch of sailors who had never been on a boat before turn the tide in the Revolutionary War? Listen, and find out!

It’s the most recognizable TV theme in America. But Jeopardy’s “Think Music” wasn’t originally written for a game show… It was written for a toddler. In this episode, we trace the unlikely journey of the Jeopardy theme, from Merv Griffin’s living room to over 10,000 episodes across six decades. Along the way, we explore the show’s sonic evolution, including honking buzzers, 80s synths, and orchestral remixes.

Children say it every day in school, but have you ever wondered why we recite the pledge of allegiance? We journey back to the late 1800s to understand how a massive wave of immigration and sagging magazine subscriptions gave rise to this vow of patriotism. From the Civil War to anti-immigrant nativism and Cold War politics, this one pledge tells many stories.
