Reason #25
Bustin' on Artoo
There's this one scene where Padme and Anakin are walking on Naboo and she says she's a little nervous and he confesses to also being nervous since this is his first assignment by himself. "Don't worry," Padme says. "We have Artoo with us." Then they both laugh about how ridiculous a concept it is that Artoo could be at all useful. Artoo beeps and if Threepio were there to translate it would probably be something along the lines of "Fuck you both."
Thats funny shit man!
