Hmm, there's my wife, a chair, a cat, a trashcan, and a tall fan with a fedora hat on top whom I lovingly refer to as "Stalin." I honestly have emotional attachments with most of those things and don't really want to use them as weapons, but I guess the chair and the trash can are the most practical so they can at least be used as bludgeoning weapons but there's the fact that I have the skeletal health of a septuagenarian and trying to lift that big arm-chair would probably snap me in half and I don't have the fore-arm strength to pound the trash-can hard enough on the zombie in enough time to face another one.
I suppose Stalin can also be used as a bludgeoning weapon or a cutting weapon if I tear off the shield, but that would make me sad. The cat has claws so if cartoon logic serves me well, I suppose I can have the cat rip the zombie to shreds. Or if Postal 2: Apocalypse Weekend rules are in effect, than when I drop the cat it'll turn into a Tazmanian Devil Cat or something like that. My wife is pretty tough but within normal human limits, so yeah, can't really use her as a "weapon."
