Well, it's July 13, and luckily it doesn't fall on a Friday. For that we can thank Roy Thomas Pope Gregory XIII for our current calendar, although hey, while we're here, let's just put any blame on Mxyzptlk. He's probably responsible!
Crisis on Infinite Earths is a complicated crossover event, so let's review the plot to date:
Goooooood morning! How'd you sleep? Did you sleep well considering the multiverse will soon be dead, dead, dead? Deader than Deadman, the deadest man of them all? Deader than Jason Todd? (Whoops, metaphor not valid after 2005.) Well, I hope you did! Sit down and have a sunny glass of fresh-squeezed Florida orange juice (never from concentrate!) while I fill you in on the schedule for our busy day of July 12: Today in Crisis History!
