YouTube user Nicholifavs wins my award for most productivity inside an Apple store. The kid films lip-sync videos from the likes of everyone from the Black Eyed Peas to Lil' Wayne--all inside an Apple retail store.
Not everyone can afford studio time, but something tells me Nicholifavs's Apple store shenanigans have more to do with shtick and swagger than cash. After all, check out the bewildered looks he gets while he's filming!
Implications - It's remarkable to me that he is clearly so young and doesn't hold back at all while recording these goofy videos. That is the kind of fearlessness most people would kill for.
