"A" firearm?!? What the hell? I've got at least three I can remember, and that's not even counting the crossbow slingshot or the BB gun.
I also own a Masai spear, a couple of rolling pins that could be fashioned into emergency nunchucks if necessary, and an original copy of Mötley Crüe's Shout at the Devil album, so you better just watch it, Yeadon. Show some respect, yo.
