I spent hours making this poster (with my trusty Photoshop). Hope you'll like it and to fill those 350 characters:

Wheat is an instrument of life. It gives us our daily bread, our cakes and especially a meaning to a cow's life. To you it might be just something that can be considered as an mediocre need but to a cow, it means every damn thing Why? You ask? Well, you see, cows were created with the desire to take all over the world. You might think, "How in the world is that possible?" I warn you my friends: Wheat is The Weapon of Mass Beef Creation. It is wired deep within their... underestimated minds to exploit the apocalyptic power of wheat. It multiplies their forces by the tens, hundreds and billions! ONE DAY YOU WILL LOOK AT YOUR FARM WITH AN INNOCENT COW EATING ON YOUR PASTURED GRASS NEXT THING YOU WILL KNOW A HORDE IS EATING YOUR VERY BONES AND FLESH. NO SWORD AND ARMOR CAN SAVE YOU FROM THEIR WRATH THAT THEY WAITED THOUSANDS OF YEARS TO CAST UPON US PUNY BOX HEADS. THEY ARE EVIL. THEY ARE FILLED WITH PSYCHOTIC WILLS TO DESTROY YOU. YOU HAVE BEEN WARNED. RUN. RUN FOR YOUR LIFE
