So these seven guys (plus the cameraman), with apparently too much time on their hands, filmed this Vine video (6-second limitation) performing a crazy alley-oop (a basketball term meaning, well, this):
The mantle was taken by these 10 friends who raised the stakes (their technique is a bit more boring but hey, it's a much smaller pool!):
And then, someone posted this video online. I am not sure if these are real or faked, but some of them are fantastic.
Are you going to try this at home? Do. And post it in the comments!
