The video below is a speed run no one knew they wanted to see. Not only does the player beat Super Mario Bros without losing a life, they do it while scoring the lowest amount of points possible. Take a look if you have about 10 minutes to spare. Thankfully, they edit out the slow waiting part at the end of the level.
Apparently they have an entire YouTube channel full of game play videos. To be honest, this is one speed run that I’ve never contemplated. Ever.
