A rogue retro-gamer at Google has apparently programmed the famous Konami code — the mother of all cheats, the giver of life and ammunition to small, spoiled children with poor motor control— into Google Reader. Just make sure you're at the Home Page, then enter Up Up Down Down Left Right Left Right B A. The result? A horizontally shrugging Ninja will pop-up in the sidebar (although I'd argue that it really should be a Contra-esque Schwarzenegger for optimal effect) and your unread items will be reset to 30... the same number of lives, of course, you'd get in the NES era once the code had been successfully entered.
