If you've ever tripped, fallen, or suddenly done anything clumsy, don't worry - it wasn't your fault. It was Mario.
Mario is everywhere - constantly messing with people and making them look foolish, all for his sick and twisted amusement. Pray that Bowser kidnaps Princess Peach again soon, so that Mario will be momentarily distracted enough to leave us all alone for a brief time.
Inevitably though, Mario will return and start knocking us over again, because Mario is just a huge jerk.
