Well, at least he is way less annoying compare to his dad. Which makes me think that his mom may actually be a nice female. Perhaps waaaaay to drunk in a party to actually think that JarJar is a non-retarded coherent human being.
On The Side Note: JarJar will not be that hated, if GL didn't try too hard to make him look funny. I mean, many of the "funny" scenes are nothing but annoying. If not for those he may actually be a semi-loved air head.
