You may think that you're safe, but this video proves that no one is completely free from the risk of getting dunked on.

I'm to the point that if I never see another dumb Vine video, I'd be completely cool with that . . . then something like this comes along.

Well done random college class room!  You've momentarily restored my faith in Vine.

The only thing that would have made that video better is if THIS would have started playing right after the dunk.
