Like all great videos that come out of Russia, this one ends with an explosion.
Boris and Ivan are having a great day on the lake with a boat filled with surplus military explosives, and what we're sure is a few crates of vodka. Ivan has his arm extended, for some reason, but Boris is the one holding the grenade.
Instead of throwing the grenade like a reasonable human being, Boris nonchalantly drops the sucker directly beside their little boat. Our genius fishermen were knocked briefly unconscious, but neither suffered any serious injuries.
