Here is a pretty funny video which is sort of a spoof on all of the California cow cheese commercials. There is a ninja guy out walking in a field and he meets up with a cow. The cow turns all even on him and attacks him ninja style. For the most part the cow beats the crap out of the ninja guy with various ninja cow moves combined with Matrix special effects such as slow motion. About four 6ths of the way through the ninja guy figures out the cows secret which is it's udders. He starts attacking the cows udders and finally drains the cow via it's udders. One inconsistancy was I thought only bulls had horns but this cow has horns AND udders. Spending a little to much time near your local nuclear power plant eh?
