"...Why a smoker would want to venture into the wild with cigs but no gas/fuel lighter is beyond me..."

Back when I was young and dumb and smoked, I was once out hunting jackrabbits with my trusty K-22 and felt the need for a smoke. Dug out my Zippo, and guess what, it was dry. Got desperate, and tried what I had seen on TV, or somewhere. Held the end of the smoke at the muzzle and touched off a .22 round. Scorched the paper. Took a round apart, sprinkled powder on the end of the cig, put the case with the rest of the powder back in the cylinder and, muzzle skyward of course, tried it again. Gave up on rabbit hunting and trecked back to my car to use the lighter in the dash. Soon got smart and stopped smoking...
