Jimmy Fallon, who has the energy and optimism of an un-jaded young child, brought actual children onto The Tonight Show last night.

In an adorable advertising move, Fallon invited child inventors onto his show (thus introducing the portmanteau Fallonventions), showing off their innovations and even rewarding them with the traditional big check. The adorable Mark Leschinsky (and his sister Barbara) presented the Eat Corder, a recorder you can blow into through your nose, allowing you to eat and make music at the same time.

(Aside: did the notes they played remind anyone else of the song "So Nice So Smart" from the Juno soundtrack?)
