Mr Prion

You want it, don't you, that nice big fat juicy steak.

What about a luscious plump burger full of protein to pump up those muscles.

Allow me to just fatten this heffer up with plenty of feed, I make my own, it's cheaper for me so I can pass on the savings to you. 

I spend my nights on the tractor dragging the rotting carcasses of the dead to the grinder, I'm not sure how these cows died, probably a brain tumor of sorts but I don't mind.

I toss them head first and watch the steal blades chop the rotting flesh into a wholesome feed for my cattle, they love it, especially the black matter oozing from the Corpus callosum, it takes a few days for the nervous tissue to decompose from the cows feces so I keep them out of sight from the health inspector, can't let that guy ruin a good thing.

Now my cattle are ready, nice and fat for the slaughter, there bellies full of the festering feed of there own kind, they are cannibals, ready to be sliced up into quarters and jammed into fresh buns for you to enjoy. 

I must say, it looks great, that red dye they add looks fantastic, now I just sit and wait, about 28 days should do it, the infectious agents will begin to fold into the proteins and drive you all mad while I feast on fresh vegetables

Well, I was never going to eat my own masterpiece. 

Can you hear humanitys bovine scream as the doctors try to fix you, it's hard to remove your spongiform brain when your kicking your hooves.
