1. The general belief is that Santa only counts naughtiness from December, although you could also say that he weighs ALL of our good and bad deeds over the entire year, and whichever is in surplus decides our being good or bad.
2. Santa runs the "mall-santa" business. All children's requests are digitally recorded and fed to the North Pole. Santa said in a press conference in October that he is considering using clones of himself by 2014.
3. Santa owns over 70,000 businesses across the world. Almost everything in your home has a "child monitor" that detects a child in the house, and immediately begins recording their actions.
4. Inflammatory religious-based comment removed. -B6
5. You know that one top-secret military base with all the rumours and conspiracy theories surrounding it? That is actually Santa's "technology-testing Headquarters." People say they're testing anti-gravity there. That is because Santa is under pressure from PETA to stop relying on the endagered angravitus reignydeerus and move on to technology less cruel towards animals. He also had a teleportation device invented in 1936, which he uses to get into all houses now, since every uses their fireplace to hold candles now.
6. Santa Claus was blackmailed by the U.S. Government to stop giving presents to homeless children, as a plot to eradicate their worthless smelly, and poorly dressed behinds from the planet, resulting in a clean world where only honest hard-working people live.
7. Santa would use the hypno-itius 3700.02.57.08 (subject to change) to lock you into a deep sleep, proceed to slap your face for thirty minutes, and would yell into you ear that he is NOT Publisher's Clearing House.
That said, I believe in Santa until I was thirteen, and I'm DARN proud of it! Child-like innocense is the best thing there is!
