I think this'll be a good chance for everyone to learn so they don't go Z-hunting unprepared.
*UPDATE*
I'm sad and very ashamed to say that I have not been on this awesome, zombie-destroying site for about two years and I'm very glad y'all kept this thread going. I want MORE. I want you Z-Hunters to get ridiculous! Thank you guys for being good sports. And remember: NO FIRE!
A monkey with a gun.
Useless beasts...never hit what they are aiming at and constantly distracted by bannas.
A mechanical log splitter is pretty useless as well. Effective only if you can get the zed to stick their head between the anvil and the maul. Then they are really effective.
Wood Chippers. Effective but atomize zombie blood into the air in an amazing splatter. Highly contagious.
Anvils, safes and grand pianos conveniently hung from a pully off the side of a seven story building. Only effective if the zombie stands on that red X you painted on the street. Perhaps with a small sign pointing to a bowl that says "Zomby Fewd"
A unicorn- Great! That horn is amazing for de-braining a zombie, but the second you lose your virginity, they run off. I'm guessing that quite a few of you would still be able to use one though.
