This totally bizarre little Internet meme sprung up out of intense boredom, just as most of the good stuff on the Internet does. The rules are simple: open your freezer door. Put your head in it. Take a picture. Upload that picture to Flickr, Photobucket or whatever image sharing site you desire, and tag it with the number "241543903." The end result is hundreds of mysterious images, all associated with that seemingly innocuous number, just waiting for some poor conspiracy theorist to discover.
