Whoever said you can't teach an old dog new tricks obviously hasn't see this video yet. Here's proof that you are never too old (or young) to completely make a mockery of the social stigma that if you are old, or past your prime, you are not worth worrying about.
Disguise a young, extremely talented sportsman (or woman) as an old person, then send them off to a street basketball/soccer/baseball/tiddlywinks—tick as appropriate—game so the said old person schools those young pretenders in how to play and humiliates them appropriately.
That's what happens in this video, and it belongs to a whole genre of videos that use this very effective and potently viral technique.
This particular video features the awesome talents of freestyle champ Sean Garnier, who runs rings around the players with his gravity-defying moves while the crowd cheers on.
