This is the $25 Nintendo Mario Figural Calendar available exclusively from ThinkGeek. You just drop the correct month, day of the week and date number blocks into the slots, and presto, you've got yourself a constant reminder of time's unrelenting march towards your death. "Or today's date." Sure, sure, that too.
Keep going for a handful more shots.
Thanks to Christina D, who agrees not knowing what day it is is all part of living the dream.
