Where's Warhol When You Need Him?

Earth Day isn't until April 19, but you don't have to wait to show your love for Mother Earth because tonight it's Earth Hour! That's right, hippies, wherever you live on the planet, at 8:30 PM you are encouraged by the good folks at earthhour.org to turn off your lights for one hour. For the planet, ya know.

But don't turn your computers off because they want you to Twitter your lights-out event to the world. Oh, and take pictures. And videos. In the dark.

Really.

As if that weren't enough, they want entire towns to "observe" Earth Hour by shutting down street lights and other "non-essential" utilities. At 8:30 PM. On a Saturday night. You can probably do the economics on that yourself.
