This is my reasoning why Jar Jar BInks is a Sith Lord. In Star Wars Episode One Jar Jar Binks falls, tumbles and looks like he is using Drunken Fist style. In a deleted seen, Jar Jar pretends to be scared about his ship sinking. However, he knows he can swim and breathe under water. Your probably wondering why is a Sith Lord acting like a fool? He is trying to fool the Jedi and he makes hand movements like a mind trick. A lot of people are saying that Jar Jar is Darth Plagueis the Wise. Look at Jar Jar’s eyes, they look like Sith eyes. Also, at his home all the other Gungans look at Jar Jar more like some one you should be afraid of instead of the town fool. He mocks Qui-Gon Jinn when he says the force will guide them. That is my theory about Jar Jar Binks being an evil Sith Lord.
