Not all farmers are marksmen, take Old Farmer Giles
(not the rhyming slang one or maybe???) He may have fading eyesight, as we all do when we get older but being a farmer, Glasses would often fall off or get broken by his animals so now he dose not wear them as he is out on his tractor and can see where he is going but not in fine detail, bad knees and back, due to all the heaving and shifting and being down in strange places (back to the rhyming slang!!) shaky hands, due to cold and the remedy of a nice hot toddy too many
(know that feeling well!)Lot's on his mind and slower reflexes due to being nagged by Inland Rev etc and managing his money, soooooooooooo, when it come to him seeing Mr and Mrs Fox, he has to be quick on the draw and to pull his gun out of the gab, take off the bailing twine that's tied it too the seat to keep it from falling off, then stop his dog from running in front of his aim and so when he gets to shoot, the Fox is running the other way and only gets a pellet or shot to his hind quarters...Oh, I knew that Old Farmer Giles!!!!
