Let's face it: everything is a lot more horrifying than you thought when you were a kid. Pick even the most childlike, innocent thing you can think of, and the odds are that there's a deeply disturbing story behind it.
For instance, nursery rhymes. We grew up memorizing these seemingly nonsense lines of verse from Mother Goose, which seem to exist for no other reason than to keep toddlers entertained. There couldn't possibly be some kind of weird, twisted history to them, could there?
Well, guess what ...
5Three Blind Mice
Three blind mice, three blind mice,
See how they run, see how they run,
They all ran after the farmer's wife,
Who cut off their tails with a carving knife,
Did you ever see such a thing in your life,
As three blind mice?
We Thought it Meant...
A trio of unfortunate rodents on a mission to find out where the hell they are, eventually run into an old woman who just happens to be skilled in chopping small defenseless animals to pieces. So this one's actually already kind of disturbing on its own.
But Some Experts Say...
The farmer's wife in the poem is an allusion to the 16th Century Queen "Bloody" Mary I, and her enthusiasm for everything involving torture, death, and basically finding new ways to go down in textbooks as history's biggest bitch. The three mice supposedly represent three noblemen who got together and said, "Gee guys, maybe this Mary lady isn't all there." and were consequently prosecuted for conspiring against the queen.
Not afraid to cut a motherfucker.
If you're cringing at the thought of what the cutting off of their three "tails" symbolizes, don't worry. She didn't cut off their dongs. No, she proved she had some form of human empathy, and simply burning those suckers at the stake instead.
