The short film "Studies In Hysteria" is definitely unique, but for the longest time I thought it was one of those vague commercials for a jeans company. Nope. It's won several awards even.
It tells the story of a man who lives in a village where everyone is naked and how his life changes after he finds a pair of pants. It's an amusing take on conformity and peer pressure.
Warning: The video shows a lot of full-frontal nudity so you won't want to watch this one at work if your boss is a prude. It's worth it to blow it up to full screen, btw. *winks knowingly*
