Underpants dancing

This is a video I made a few weeks ago, inspired by keri smith (from Wish Jar Journal) using my new MacBook, and the software in it for iMovie. (Adam thinks I did too much with the stills, and maybe I did, but I was learning and playing with the program) .
Emmett is a pretty funny kid. He did "underpants running" all winter last winter, and I was lucky to get some footage of this too....
