Unassuming teenager shocks crowd by winning high-school dance-off (VIDEO)

That old saying 'You can't judge a book by it's cover' has never been more true than in the dance-off you are about to see in a video below.

A skinny, teenage boy in Napoleon Dynamite glasses goes from unassuming and somewhat gawky wallflower to dance floor god thanks to a few insane moves.

As a New York high school crowd gathers around the dance floor with cell phone cameras at the ready, one cocky dancer wows the crowd with his fancy footwork in the seemingly 'all over before it's even begun' dance-off.

Then, after a few friendly prods to his nerdy looking opponent named Kevin, the crowd waits in giddy anticipation of what most expected to be the worst dance routine at Yorktown High School history.

But imagine to everybody's shock when the McLovin’ lookalike pops a few insane moves and kills it.

The winner of the dance-off is clear from the clip that's blowing up Twitter. Even the videographer spins the camera around in shock at what he just witnessed.

As the crowd screams in delight, the young man who went first acknowledges 'the winner' and grabs Kevin for a celebratory hug.

Stereotypes be damned. Pretty awesome.
