This whole thing really only hit me when I was having a star wars marathon with a few casual star wars fans (meaning those that don't browse star wars boards like us). When that scene came up and Obi-Wan said this line, they just laughed a little and said "uh... no".
But I guess this edit is mostly for die hard fans who care enough to post on this board, so then it doesn't matter, I guess.
Edit: Just for clarity, Sevb32, maybe it's because english is not my native languish, but if you had said "the english teacher" I would have assumed that it was your only english teacher in high school. But again, maybe that's just me.
