The commercial is very silly, but even without it's corny song emphasizing it the whole idea of Mario running around with a glorified water gun cleaning up pollution was enough to turn me and my friends off from the game. We all played it and loved it once it was out, though, nobody can resist a 3D Mario platformer, no matter how much we continued to make fun of it. But I digress, I wouldn't call this the dumbest thing in the history of the universe, or even the dumbest thing in the history of Mario games- that is a seriously difficult thing to pick. There's been the CDI spinoffs, the cartoons, the educational games back in the SNES days... Lots of dumb stuff!
