Almost everyone has heard the joke about using a grenade to "catch fish", but I don't think anyone has been dumb enough to try it until now.

Two Russian men in a boat set up to film what would happen if you dropped a grenade over the side of a boat, and hilarity ensures. They had people on a separate boat filming the entire scenario, so the would could enjoy the "brilliance" exercised in this stunt. Check the video below.
