Consider yourself warned — if you start exploring Ze Frank, you will lose 8 hours to it. It's addictive...

Ze (pronounced "zay", short for Hosea) rose quickly from obscurity to world fame a few years ago with his viral e-mail "How To Dance Properly," a series of short looped video clips that the Brooklyn-based artist and Web designer sent to friends as an invite to his birthday party.

He's since done lots more videos, including advanced dancing and this clever one, on e-mail communication.
