The people who support this show on Patreon, the real heroes, they get some really cool stuff. Like bonus shows full of ideas that might be considered too niche, like a brief history of paint. Which is a tale that contains way more proto-German mad scientists than you're probably expecting. 

The people of Patreon were generous enough and thought this show was interesting enough, to share with the rest of the world. Consider this to be a teaser, a taster, a 'first hit is free' trial run of the awesome stuff you have access to if you help keep the HGT lights on.
