If you guys have heard of Diablo 2, (its a computer game), towards the end of the game, you can open a portal to a cow world were there are a bunch of cows walking around on their hind legs with giant axes.
Suprisingly the cows are incredibly hard to beat. And there is this one special cow called the Cow King. He can drop really rare items when you kill him, but hes always surrounded by a crowd of other cows at least 5 deep.
