Now it may be considered G-level canon EU that Obi-Wan's home planet is called "Stewjon" named after Jon Stuart Leibowitz who shortened his name to John Stewart to show he was ashamed of his own heritage before the all-powerful Hollywood elite. So either the homeworld is spelled "Stujon" or it must be a pun named after the infamous restroom scene in Fanboys.
Raaaaaaaaaacist!
