You can see Fallon losing his shit.
After showing off the Mario endless runner, Super Mario Run, Jimmy Fallon then got to do what just about everyone has wanted to do over the last few months: get hands on with the Nintendo Switch.
According to Nintendo, all of the games are stored on the console itself. There wasn't a great deal of information, although the game appeared to transition smoothly from being in the dock to the portable mode. It also appeared to run pretty smoothly in tablet mode, with Fallon belting a couple of enemies for good measure.
