Signs. They're literally everywhere. Most of them are pretty easy to disregard, which sort of defeats the purpose. A sign is supposed to capture your attention to communicate an important message. Maybe that's why signs that warn of danger are so freaking scary. It's hard to ignore a sign that's like, 'Hey, you! You're gonna die if you come any closer!' Some signs are so ominous that they're almost funnier than they are intimidating. We've got a bunch of examples of comically spooky signs that we never want to come across IRL.
