"In the Late December" (MP3 link), by Greg van Eekhout, is a Nebula award-nominated story about Santa Claus and the end of the universe, and is Escape Pod #138. (By the way, this is a very dark story -- there's no sex or violence but this probably isn't suitable for kids, where "kids" is defined as a stereotypical aggregate of child-like characteristics. Yours may be different.)

Sober Santa. Too much politics today, not enough Christmas fun. Here's a drunk Santa game from b3ta. Pretty tough once you get going.

Santa Claus, elusive jolly old elf, has finally been located by someone curious enough (in both senses of the word) to use FedEx to track him down. (The page I linked to here only tells half the story; click that link down on the left to get FedEx's tracking page.)

Santa Claus is Coming to Town, and the US Military is watching him. It's NORAD's annual "Santa Tracking" PR campaign, reporting that Father Xmas appears to be flight testing his reindeer earlier this year (a prudent move, if you've seen "Olive, the Other Reindeer", my new favorite Holiday TV trifle). No Grinch sightings, however (he's gotten enough publicity, thank you). Now, the only unanswered question is: Will W.'s proposed Missile Defense System (TM) pose a risk to the Clausman? (And are Rogue Countries (TM) making missiles shaped like sleighs?)
