Ok, i may have missed quite a few things along the way, but how did Mario end up jumping platforms and killing everything from goombas to bowser? I thought he was a plumber, do most plumbers jump on people's heads to save princesses? It's something I was curious about, and since Gametrailers has yet to release a retrospective for the Mario series, I thought I'd ask here.
Edit: Just found out. Apparently he got sucked down into mushroom kingdom on a job? You see what happens when you don't own an NES?
