There are varying opinions on this guy, but I think he's hillarious. The name pretty much sums it up, he's a nerd who reviews really shitty video games, and therefore gets very angry. Watch his videos here:
Caution: the videos do contain repeated profane language, so you might want to prevent the kiddies from seeing them. I especially recommend the Spiderman one, which is really funny and was a lesson for me, since I bought the Spiderman game for Game Boy that was shown on the video. Probably the worst 5 dollars I've ever spent, truly a shitty-ass game.
