As the show's very own odd couple, the pair saw their way through some ridiculous disagreements, various neuroses, and one very long contract. If you're a fan of "The Big Bang Theory," you might think you know everything about Sheldon and Leonard's friendship, but there's a chance you don't know it all. This is the Sheldon theory that changes everything on "The Big Bang Theory."
