This beats my theory that Daniel Radcliffe and Harry Potter are actually two different people.

Yes, I know fan theories are never true and they're usually concocted by people with way too much time on their hands, but there's something I absolutely love about them. There's nothing like finding (and stretching) all the little pieces of evidence that prove the Rugrats are actually dead or Ferris Buller is a figment of Cameron's imagination. As a global phenomenon, Harry Potter has been subjected more than most properties to such crazy speculation. (For example, if you're ever bored, go through this page, and you'll discover all the insane ways people thought the series was an allegory for global politics in the early 2000s.) The latest Potter-centric theory to go viral, however, deals with "The Tale of the Three Brothers," a fictional folktale that appears in Harry Potter and the Deathly Hallows.
