I can't believe I've never seen this before. Remember when Daniel recreated Level 1-1 of Super Mario Bros.?
Well, someone took the original video of the guy who broke his arm trying to climb some homemade crate-stairs Mario-style and animated Mario in there. Genius.
It's kind of like Mario doing his take on our "I'm better than you, na-na na-na boo-boo, stick your head in doo-doo." You show that broken-boned loser, Mario.
