If you really take an honest look at Mario, he's kind of a dick. The guy keeps his brother in his shadow, is constantly objectifying the Princess, and goes around needlessly stomping on poor turtles.
This is exactly why it's reasonable to believe that if Mario crossed over the real world, he'd be going around knocking cats into toilets and causing skaters to wipeout. Does the guy EVER do any actual plumbing?
