Watch this incredibly smart short film, called "Food Fight". It is the history of modern warfare from WWII to the present as re-enacted by food (Japanese are sushi, Americans are hamburgers, etc.). The director, Stefan Nadelman, describes it as a "smorgasbord of aggression" and you'll see why. (The end is particularly effective.) You might have to watch it more than once to successfully identify all the battles, but it's worth the effort.
