I'm generally not a huge fan of anime music videos, but when they are done well I can't resist. This one was shown to everyone at the last PSU Gaming Club meeting. Apparently it debuted at Anime Boston 2007 and it's quite appropriate. You'll know when you see...
In case you don't get why this is so funny, remember this debuted in Boston. The little guys are mooninites. Oh, and the 1812 Overture (the music) was the first classical composition scored to include actual cannon shots, so the explosions you hear are SUPPOSED to be there. ;) It was also the piece playing over the loudspeakers when V destroyed Old Bailey in the movie version of V for Vendetta.
