R2-D2 has always had a knack for getting C-3PO into trouble. Such is the case when the two droids stumble upon the massive droid factories on Geonosis. An impatient Artoo accidentally knocks C-3PO onto one of the conveyor belts, where he is filled with a new droid head. The usually cordial Threepio briefly takes on a new, more aggressive persona until Artoo makes sure that his counterpart doesn't lose his head anymore.
