Have you ever wandered one step too far into the internet and been left scratching your head (the one at the top of your body), wondering what the hell is going on? If you have, chances are you've stumbled upon a "meme," a bizarro inside joke of nerds and shut-ins that eventually slithers its way out to the mainstream world. You know, like that "Chocolate Rain" song or Chris Crocker or Ninja Cat. Just weird oft-emailed pieces of driftwood that (having replaced The Outdoors) fill our idle hours until we gasp, sputter, and expire. To keep you informed on the memedium, a timeline site has sprung up, giving you a brief historie of these useless fascinations. Quick for larger screen grab.
