Autumn Fischer and Greg Russ are tackling life’s big issues one topic at at time. A whole episode dedicated to salt? Sure, they’d be open to that. A discussion about that old movie you wouldn’t think anyone would ever feel the need to talk about in-depth? Already done it. If you’re a thoughtless chump who holds no curiosity for the world around you, don’t waste your time listening to this podcast. But if you’re self-aware, smart, and fall for reverse psychology, One Topic is the show for you.
