... the proper and safe way to light a fart is to start with an old wet t-shirt .... and a clump of vaseline ...
... slice/cut a small hole in the shirt, soak it in water, place it carefully over your arse ... align the holes .... apply the vaseling to your own hole throught the t-shirt hole ... and you are ready to begin ...
... use a long (fireplace) match ... let rip and laugh ... the wet t-shirt (if properly placed) will prevent you from burning your butt and the liberally applied vaseline will protect your bunghole ...
... any redneck should have known this ...
