Well, the thing is like this:

Edgar,a 11 year old kid, during his holy-week vacation went to El Vallecito. He, his cousin Fernando and another dude (maybe an uncle or so) were crossing a river... the outcome of this was the most watched video at www.youtube.com

I have absolutely no clue of why or how did this video become so famous... but it even came out in tv, newspapers, fan sites, flash games, t-shirts... you name it

and now... Edgar Falls!!

Dont forget to perform the search i left for you: "edgar caida"
