   Y2K
2. It's gonna be crizzy up in hizzy!
   The Mayan Prophecy Fulfilled

Y2K was a computer bug that potentially would shut down anything that was operated or controlled by computers. This bug had to do with computers being able to recognize 99 as 1999, but not 00 as 2000. Billions of dollars were spent to prep computers across the world, and that preparation helped prevent the cataclysmic failure that was most likely going to happen.
