When I was a kid my dad made me go to a hunter safety class. You had to watch these horrible cheesy movies about hunter safety. Think Blood on Asphalt but for hunting. There is this great scene of two boys running across open fields holding their rifles by the end of the barrels as they run. They jump a fence and the trigger guard of one of the boys rifles gets hung on the fence. The boy turns around looks down the barrel and starts tugging on the gun to free it. It goes off.
I'd like to find that movie and make an anigif of that last part.
