Unfortunately, Washington's widow Martha rejected the plan to bring her husband back and the probable brain-eating rampage that would follow. Thornton backed down, but spent the next 20 years hating himself for not going against her wishes and doing it anyway. To be honest, we think history is poorer for it, too. Hell, think of the monuments we'd have today if the father of America's final act had been to chew open the skulls of his loved ones before his maid was forced to hack him to pieces with an ax.

This led to the term "Waterloo Teeth," which were infamously taken from the thousands of English, French, and Prussian soldiers who fell during Napoleon's last waltz. According to the BBC, the below specimens are precisely that: real-deal teeth extracted from the skulls of Waterloo's dead and dying.

The American Civil War led to what tooth farmers call "a good harvest." Teeth from fallen Union and Confederate soldiers were shipped to England "by the barrelful" to be made into dentures or sold individually. And so it was common for a Brit to spend the rest of his life running his tongue over teeth that had been pulled from the mutilated corpse of a young man who'd died screaming on a battlefield. And then they sipped their tea and thought, "Yep, the times we live in are horrifying as fuck!"

So this guy was chained to this hunk of searing hot metal, his skin being fried off of his body, and then Phase II of the punishment kicked in. While Dozsa was still kicking in his smoldering throne, his fellow rebels -- who had all been starved beforehand -- were forced to "bite into his burning body" and "drink his flowing blood." Yeah, this is one of those situations that make you happy that cameras didn't exist back then.

They didn't even let them choose white or dark meat.

According to that picture, some dudes were playing the bagpipes the whole time, and we absolutely believe it. A captured rebel strapped to a burning chair, screaming as his flesh sizzles off his body while his former loyal friends and comrades rip off ragged hunks of his skin with their teeth like the fucking Walking Dead? Of course they made a band provide theme music. Hey, we bet the entire time you looked at that pic, you didn't even notice that at the very bottom, there's a dude lying on the ground with a massive spike that's been driven up his asshole until it popped out of his shoulder. Why wouldn't there be?

... "cannibal" is probably not the first word which comes to mind. Or maybe it is -- we probably should have found a less creepy picture. The point is that he was totally a cannibal, as were some of the most esteemed scientists and aristocrats of 1600s England.

You see, powdered human skull was a common medical prescription for those who could afford it, for everything from dysentery to epilepsy. The same went for human fat, powdered mummy, moss from a dead person's skull, and even fresh human blood -- which one priest had a recipe for making into marmalade. Noted brain scientist Thomas Willis even had a famous medicine made out of powdered skull and, no joke, chocolate. Of course, it was all probably a placebo effect; you can't help but feel a bit better after consuming someone else's fucking cranium. "I don't know if this is clearing up the infection, but it just feels right, damn it!"

Sometimes you feel like founding neurology. Sometimes you feel like cooking up cranium cocoa.

And where did all these medicinal body parts came from? Graveyards, battlefields, executioners, etc. Where else? The past was littered with corpses like they were cigarette butts -- people would probably trip over that shit. As for more exotic ingredients like dried flesh, African sandstorms regularly provided bountiful harvests of jerky.

Clearly, nobody at that time was too worried about hauntings, is what we're saying. Then again ...

Abraham Lincoln's wife, Mary Todd Lincoln, lived a pretty miserable life. Three of her four children died before adulthood, to say nothing of a theater hack taking out her husband. Basically, everyone in Mary Todd's family was having a great time hanging out in the Great Beyond, while she was left alone and depressed. It's no shock that she would give anything to reach out to her loved ones again.

So she became obsessed with the occult, as one does. Specifically, the spirit photography of William H. Mumler, who took this photo of Mary Todd in 1871, which also appears to show ... somebody else.

Do you see it? It depends on your monitor settings. Here, let's adjust the picture:

No, we're not saying that Honest Abe came back to haunt his widow. Photo manipulation seemed like magic back then (hell, cameras probably seemed like magic), and with so many people dead thanks to the Civil War, men like Mumler made a good racket preying on mourning widows like Mary. Though we should point out that the fact that Mumler was a fraud doesn't mean that the ghost of a dead president isn't standing behind you right now.

Don't bother hiding your disappointment if it's Warren G. Harding. He's used to it.

Mary Todd Lincoln sure as shit thought there was, and presumably believed it for the rest of her days. This is what life was like in the past: A president dies and they're like, "Okay, do you want to try to reanimate his corpse, or just be satisfied to have him following you around all the time, running his ghost hands all over your body?"
