We reported earlier that Nintendo of America president and chief operating officer Reggie Fils-Aimé would be appearing on The Tonight Show with Jimmy Fallon to show-off Super Mario Run, Nintendo’s first Mario game released on third-party hardware. What we didn’t know at the time was that he would also be debuting the Nintendo Switch, giving Fallon a chance to play The Legend of Zelda: Breath of the Wild.

During the broadcast, Fallon said “I’m freaking out,” no fewer than five times, especially when it was revealed that Mario creator Shigeru Miyamoto was also in the audience, and would be watching his performance in silent judgement.

Fils-Aimé guided Fallon through a Super Mario Run level, promising to help him find an invincibility star. “Miyamoto are you watching?” Fallon shouted as he played, like a prideful child to a parent right before they do something stupid.

Pacing back and forth, faltering in his speech, shaking his hands, and slapping the desk, Fallon seemed genuinely excited at having the chance to try these games for the first time.

During the Legend of Zelda: Breath of the Wild demo, Fils-Aimé rolled a boulder off a tower into a pile of explosives to kill some goblins. He then showed the Switch’s ability to be removed from its housing and used as a portable device. At this point, Fallon took over.

“There should be a kickstand in the back, can I just pull it out? There’s a kickstand, you pop this out, I pull out these two controls, I give one to you, and we can play a two player game.” Fallon put down the Switch and threw his arms up. “No, this thing is three- IT’S THREE CONSOLES IN ONE CONSOLE. I am FREAKING out.”

You can watch the full broadcast above, and stay tuned below for Shigeru Miyamoto himself joining The Tonight Show’s house band The Roots, to play the Super Mario Bros. Theme.
