Thats absolutely retarded. Had his feet landed 6 inches farther away from the wall, he would have smashed his face into his knees.
But I guess thats besides the fact that had he not landed on his feet, he would have been asking for many broken bones, paralyzation, and possibly even death.
To me, these kids did not look like professionals with supervision. Similar to russian roulette in my opinion.
I guess its entertaining for what its worth though, other than that horrible music they put in the background.
