Batman: Arkham City's Calendar Man always has something special planned for the holidays. He's just cool like that.

Unfortunately, those special somethings usually involve murder. It's a good thing he's behind bars, then, right?

Head to the basement of the courthouse in Arkham City today if you want to hear the villain's latest sordid tale. You'll get an achievement if you listen to every one of his stories, but you have to visit on every major US holiday. We reminded you on Christmas and we reminded you on Valentine's Day—hm, feels like we missed some.

You can always just change the date on your console. Let us know what you think of Calendar Man's Mother's Day gift in the comments or on Twitter.
