I'm a huge fan of very poorly made counterfeits, and the video here features something that would surely get my vote for Poorly Made Counterfeit of the Year - 2007. If you've spent any time playing Super Mario Brothers, you'll recognize most everything here, but something's... just not quite right. Actually, make that several somethings. In fact the sheer number of ways this thing goes wrong had me laughing out loud for minutes.
