The credit card shotgun: because evidently we've run out of ways to kill each other

They're billing it as "the ultimate self-defense weapon": a credit card-sized double-barrelled shotgun that is just half an inch thick, can fire off seven standard steel BBs from each barrel, costs only 99 bucks. Better hope those 14 BBs do the trick, too. Since this thing is a muzzleloader reloading it means you have to measure out the gunpowder,
pour the BBs into each barrel, tamp in a small wad of paper, and then pray that your first couple of shots did more than just enrage your assailant.
