Video about making games within games (SOLVED)

I remember seeing such a video on YouTube back in like, 2012 or 2013, exact year I can't remember. It was a guy talking about how he & his friends who would make up games within video games. For example, in Super Mario 64 they would have a "game" in which they pretend that one of those orange boxes was a pizza & they'd have to deliver it up the hills. Not sure if it was to Chain Chomp or King Bob-Omb, but maybe it was the former. Otherwise I don't remember much about it.


EDIT: SOLVED! Thanks sonicfan2005!
