Have you played MariO, the reprogrammed Super Mario Bros. 1 with a portal gun? I have, and it was really awkward to control, so I didn’t play very much. But a bunch of guys from Rooster Teeth, the team that makes Red vs. Blue, have decided to play 4-person MariO and it’s hilarious. If you can stand watching other people play video games, this 20-minute video is a blast. It’s funny from beginning to end as these guys deal with the utter insanity of cruising turtle shells and 4 separate sets of portals.

Totally worth a viewing.
