GI Korea has a picture of a guy who takes the whole Dokdo thing way too personally and stabs himself in the stomach (warning, not for kids). If that is not good enough for you, Jeff at RIK has a bigger picture. If Japan actually did what Korea wanted every time a Korean did something stupid like this, the Koreans would have half of Japan under their control by now.
Idiot (Yeah, I'm talking about you, Yang Bong-ho).
UPDATE: I should have guessed that the Big Hominid would be on this one.
