“Feed a man a fish and he’ll eat for a day, teach a man to fish by swinging a loaded rifle by the barrel and he’ll shoot himself in the dick.”
I forgot who said it, but that wisdom still holds true today. Clearly this poor fellas never heard it because that’s exactly what he is about to do. Go whack-a-fish with a loaded rifle. A lot of the comments suggest that the sound was added and it’s just an air rifle, but either way, this is 100% NOT how to catch a fish.
