Only a master of "the force" would be able to pull off all of the antics he did at the battle on Naboo and have each and every "accident" somehow work out to his advantage. Like Jackie Chan doing "drunken style" kung-fu, it only looks incompetent to someone who doesn't know what they are looking at. Some forms of ninjutsu also included techniques for use in public situations for hiding from observers the fact that you were giving someone an ass-whooping while at the same time seeming to be trying to help them.
