You know what's a terrible thing to do?

A terrible thing to do is to fall asleep while reading Final Crisis. Seriously, you will wake up and not even know what hemisphere you're in. Particularly since you won't have fallen asleep all at once, but in fits and starts, while sort of reading two or three pages that shift transitionless between context-free scenes, characters you forgot existed and Mary Marvel scalp-stubble. It's horrifying.
