This week on A Little Knowledge, Joe and Jackson put down the research and start telling each other jokes. And somehow, Jackson's Uncle Dewey ends up becoming the star of half of them.

We trade jokes, see who can actually make the other one laugh, and discover just how many punchlines can involve one unsuspecting uncle. Then Joe reaches way back into the family history to tell the completely, absolutely, definitely true story of how his great-grandpappy met Billy the Kid.

Jokes, Uncle Dewey, questionable family history, and very little actual knowledge. Pretty much exactly what you'd expect from A Little Knowledge.

This week on A Little Knowledge, we're talking about something almost everyone does—swearing.

Why do humans swear in the first place? Why do certain words feel so much more satisfying than others? Joe and Jackson share some of their favorite swear words, talk about where our colorful language comes from, and dig into a little of the history behind profanity.

And because apparently swearing wasn't enough, we also travel way back to take a look at the earliest known written joke—proving that humans have been trying to make each other laugh (and probably offend each other) for thousands of years.

It's language, history, bad words, ancient jokes, and just enough actual information to be dangerous. In other words… A Little Knowledge.

This week, Joe and Jackson dive into the surprisingly fascinating world of swearing. They swap stories about growing up, the role bad words played in their families, and how their early exposure to profanity shaped the way they think about language today. Along the way, they explore why humans swear, why certain words carry so much power, and whether cursing is really as bad as we've always been told.

The conversation then takes an unexpected turn into classic '80s comedies like The Three Amigos and The Jerk. Are these movies still hilarious, or have changing social norms and cancel culture changed the way we watch them? Joe and Jackson debate whether comedy should be judged by the standards of its own time or by today's expectations—and, as always, they don't pretend to have all the answers.

From childhood memories and family traditions to profanity, nostalgia, and the evolution of comedy, it's another episode filled with curiosity, laughs, and just enough knowledge to get everyone arguing afterward.
