Karate Kid was a pretty good movie. I really admired Sensei Kreese of the Cobra Kai dojo. He taught his students the right way to approach any challenge: "STRIKE FIRST. STRIKE HARD. NO MERCY." Do whatever it takes to get your way. Win at all costs. Now that's a teacher. As you can see above, he makes Little Dick smile.
Mr. Miyagi, not so much. The best he had to offer was "wax on, wax off," part of which I get. I don't really get the whole "wax on" thing, but George W. Bush wax off ALL the time.
