If you haven't played Arkham City yet this year, we can only assume Santa brought it down your chimney this morning. Either way, you're going to want to excuse yourself from your family for a while to go talk to Calendar Man, the villain in the basement of the courthouse who's got a different tale to weave on every major holiday.

Today's is no less chilling than the rest, and besides, it contributes to the "Storyteller" achievement, which requires you to hear all 12. Of course, you could just change your system's internal clock, but if that creepy bastard Calendar Man asks, you didn't hear that from us.
