Where we talk about the mistakes we made and the details we couldn't quite squeeze into our series. With questions like, did Frederick really have a Harem? Who really called Frederick the Antichrist? And which person digested their meal faster in Frederick's science experiment?

Brief barnyard animal update: my friend's two cows gave birth to two male calves in the end which have been graced with the names "Dave" and "Dennis." Lambing season has just started and I counted a grand total of five sheep in her lambing tunnel, one of which gave birth while I was there but I didn't actually see it in the act of giving birth. I am looking forward to the history of cats when it starts; I doubt our cat will be watching, however, since YouTube, for some bizarre reason, doesn't include cat language subtitles, and I have started reading "The Three Musketeers" by Dumas recently. I've also been reading about some of the new expansions for Hearts of Iron IV and Crusader Kings III [I hear they're planning to expand the in game map to include China], and we were slightly concerned about our 11 year old yellow Labrador, since he appeared to have sprained his paw while he was out on a walk earlier this week, so he's been to the vet's.

We would love to always be 100% accurate but with the nature of humans, we're just going to make mistakes now and then. So we always appreciate the keen eye of the community to help us out!

Hey Extra History I just now noticed the lies episode here on Patreon I do appreciate the shout out for correcting some mistakes during your first episode on Frederick II but it was as soon as I saw the mistakes I was like Ooh I should comment this to the creators so they would know, but because I was watching from Nebula I do remember that Nebula doesn't have a comment section so I couldn't just comment these errors on Nebula even though I would love to, so I decided because I wasn't on your Patreon I thought I could use YouTube on whatever latest video/short you made and then comment the error on that specific later video, and am I lucky that I got noticed, but yeah sometimes you need that community to correct some mistakes made during the 1st phase which is uploading and testing people's awareness on the video and getting them to share their opinions with you so essentially I figured since I noticed these errors it was wise to get them noticed on Lies, because sometimes the speaking is hard to change but to get them noticed is bigger but I do appreciate the kind comment.
