What's a zombie? Never seen a real one, oops, I forgot, I think there's one at the white house.
Genetically engineered and modified plants are your best defense against zombies. Though difficult to obtain and slow to reload, the "corn cannon" is undoubtedly the most effective deterrent, with the "blue cabbage catapult" a distant second.
HaHa - I personally like the freezing watermelon but the corn cannon has its place.....
