In the beginning, there was this image macro of the spy from Team Fortress.
Anonymous saw it, and knew that it was lulz. But like Paradise without jailbait Eve, there was something missing. So Anonymous (RENRGY)(don't wanna be all "MADE I MEMEMEME") /b/-gat the MSPaints.
Anonymous saw it, luld some more, but it was still not epic. So he added some Tom Green, but that only plateaued it. Then Anonymous thought "hey, how about I make an official holiday for it?" And, like Christmas, it was a huge success. Except the holiday existed before the original. And lo, thus Anonymous realized he had divided by zero, and the universe began.
