I can't say this enough times but everyone would not be anything without R2 I mean really. Anakin wouldnt be anything but a mommas boy, Luke would be a farm boy, Obi-Wan would be some old crazy guy, Yoda would be a Muppet (maybe like kermit the frog). R2D2 makes everyone look bad at times... Like when he kicked those droids ass while all of the other Astro Droids wimped out and got their head torn off. And C3P0 was a real jackass. He had no appretiation for R2. And he wonders why he gets a Memory whipe!! If that stupid proticol droid kicked ME his master I would kick that droids butt!!
