Jan Svankmajer is a highly influential Czech stop motion artist whose work you've seen echoed a lot in the Quay Brothers and Tim Burton. He did a nifty little trilogy centered around the gnashing of foodstuffs with broader themes of class oppression, although its more fun than we just made it sound:

Jan Svankmajer's Food (Part One - Breakfast)

Jan Svankmajer's Food (Part Two - Lunch)

Jan Svankmajer's Food (Part Three - Dinner)

Also, here's Zamilovane maso (Meat Love), which is fantastic but not part of the above dealings. You may remember seeing this on MTV as a interstitial back when it gave a shit.
