Well, don't watch the M&L 3 ad until you've beaten the game. The advertisement is, in fact, atrocious and I have no idea why Nintendo keeps choosing to make the American commercials appeal to kids 9 & under.
What's very ironic is that the commercial has a lot of fat 11 year olds talking about "kicking germs' butts" and "Bowser inhales a vacuum shroom RAAAARGH LOL HEHEHE" but the game's dialog/etc. is definitely geared toward young adults & up.
Seriously, name one kid on that stupid ass commercial that would know what "discombobulated" means, as an example from the game.
