Dog bombs. Horse treadmill trains. Coffins with periscopes. A group shaving machine. Some inventions are brilliant. These are absolutely not.

In this history-meets-hysteria episode of The I Digress Podcast, Ringo throws us into the worst investment round in history – think Shark Tank, but lethal. From Soviet war dogs that accidentally bombed their own trenches to the "youth serum" that straight-up killed its inventor, it’s a comedic catalogue of chaos. Also featuring: a bullet-loaded mousetrap, a lighthouse that wiped out its builder mid-storm, and a childbirth invention that flings babies out at 7G. Yes, really. Laugh, cringe, question humanity.

House sharing chaos that everyone can relate to. In this short but savage episode, the boys relive house sharing incidents from dodgy Edinburgh décor and vitamin overdoses to incest-adjacent bed-sharing and beds dubbed The Chariot and The Boneyard. If you've ever lived with friends (or frenemies), this one's for you -- complete with prank calls, soggy sheets, and cheese toastie addiction.

Nuclear survivors, meth-fuelled ski escapes, public barrel-wanking philosophers, and vampire opera singers - it's your history lesson, I Digress style.

This fact-filled romp through bizarre biographies uncovers the most jaw-dropping lives you’ve never heard of. From Diogenes the Cynic publicly peeing on people for “philosophy” to Julia Child’s double life as a wartime spy-slash-chef, no tale is too weird. Also featuring meth-fuelled Finnish soldiers, undead French divas, and a “gentleman’s club” that’s basically just old blokes wanking on silver platters.

• Diogenes: Ancient Greece’s original troll – lived in a barrel, insulted kings, and used his hand as a cup.

• WWII's Julia Child cooked up shark repellents before soufflés.

• And yes, there really was a secret society where nobility… anointed the furniture.
