He's on the coolest hoverboard ever and he goes: "I wanna get off "

[@Dylan-gs9sm]

This should go viral

[@DitchyDimana]

"I'll be careful, don't worry, I got a hammer" that's a sentence I thought I would never hear in my life.

[@shenol369]

Learned more from this man than I did in all my years in science.

[@mariav9445]

Jimmy is so adorable trying to catch these things at the end when they explode!
