We've mentioned before how Disney parks aren't strictly rainbows and tri-circled sunshine. While you and your family are waiting in lines and posting Facebook pictures to brag about how much fun you're having, there are secrets hiding all around you.

As you walk through the gates of Disney World, you're probably so overwhelmed by the magic of childhood that you don't notice that you're walking up an ever-so-slight incline. That incline is there because you're on the roof of a ground-level tunnel system -- and you're one story in the air. By the time you reach Cinderella Castle, you've actually made it up to a third-story level. That's because Disney World was built on top of a huge series of tunnels and rooms called utility corridors, or Utilidors.

In case you ever wondered what the Death Star would be like if it were 400 percent more whimsical.

Shortly after Disneyland opened, Walt Disney realized that it looked kind of odd when he had cowboys walking through Tomorrowland and astronauts walking through a Renaissance fair. When it came time to build Disney World, he wasn't having none of that shit. Before any of the park pavement went down and before any of the rides went up, Disney had a series of tunnels, dressing rooms and secret doors built first. And everything else went on top.

"Disney World is finally complete, the culmination of my life's work oh shit we forgot to build air holes!"

But the fact that you're walking on top of a secret city isn't even the sinister part. If you've ever been to a Disney park, one thing will stand out: It's clean. Thousands and thousands of people are all around you, most of them kids, and there is zero trash on the ground. No sticky gum residue, no used condoms or old panties to be seen anywhere. Everything is clean. Have you guessed why? Because people are popping up out of the ground to clean that shit up, like mole people, quickly disappearing back into their subterranean kingdom with you none the wiser. The only way to figure out where they're coming from is to casually dump a purse full of fingernail clippings on the ground and stand aside to watch what happens.
