A person who won't use a gun or a knife might use a hammer..but who said those tools were for killing the cow? And...cows ain't got no thumbs or fingers, so they couldn't use a gun...and I know proper butchering technics, but it IS a cartoon, and even the artist has said that sometimes when he gets done drawing the 'toon he doesn't know what it means.
Now that you mention it, those cows couldn't use ANY of those tools.
