According to the theory, Jar Jar is the evil equivalent to Yoda in Empire Strikes Back, an extremely powerful Force user playing the fool. I’ve taken a look at Jar Jar in Phantom Menace and Yoda in his first scene in Empire; there are very interesting similarities.
Making a mess
When Yoda first meets Luke Skywalker, he finds his way into the young Rebel’s supplies, and starts “making a mess”. Luke takes one piece of equipment from him, and Yoda keeps rummaging around and throwing stuff all over the place.
Interesting similarities. With Lucas’ “rhyming” motif in mind, you can observe Yoda and Jar Jar’s identical behaviours towards technology and conclude that Jar Jar, much like Yoda, is playing the fool and hiding just how smart he actually is.
Messing with R2-D2
In the same Empire scene, Yoda meets R2-D2, and ends up beating the droid with his cane. Again, Yoda is pretending to be an old alien fool and that’s why he goes to the trouble of antagonising a droid.
Similar reactions to R2-D2’s teasing in both cases. We know that Yoda doesn’t really care about the torch he’s stealing from Luke, he’s just keeping up his fool act. Does Jar Jar really care about R2 bumping into him while he’s going outside to save the ship?
