River surfing, powered by dynamite

This video seems vaguely hoaxy to me, but not completely implausible, so I'm going to just accept it as legit because it comes from Quicksilver. These dudes throw TNT into a river and then their buddy paddles into the little waist-high wave that results. Awesome idea and execution. Not as sweet as the guys who surfed the waves caused by the calving glacier in Alaska, but commendable nonetheless.
