As a serious topic, this needs to be discussed in great detail. Over time, as many movies and historical documents have shown, the zombie virus is carried in bodily secretions, most notably, blood. Due to the messy nature of how zombies don't want to die typically, and are quite persistent in sticking around to try and "convert" you, a bashing of the brain and/or heart is usually required. Sadly, the bashing that must ensue causes gashes/cuts/abrasions to the scalp and various other parts of the body, leading to these infected fluids to spill out, and in all likelehood, onto you. Bloodborne pathogens are no joke people.
Therefore, the weapon of choice must be thought about wisely. I have seen many of you choosing hand to hand combat items, items that would bring you into the "splash zone". A weapon that is either ranged in nature, does not expire as time wears on (bullets run out people), or cauterizes the wounds as they are inflicted are best to be chosen. In an unrealistic world, or the one where zombies infest malls, a lightsaber would serve best.
