I liked the fan theory that Jar Jar was a secret Sith Lord. It makes him more interesting and gives you a reason to dislike him beyond being annoying.
One variation compared his antics to the drunken kung fu master style. And he’s moving his hands while manipulating their minds. It would be one of the only reasons to include such an idiot in the Senate. But no, they replace him with dull white guy Count Dooku.
