Maria Popova celebrates Dr. Seuss's nude "adult" book. It's long out of print but not too hard to find.
Wishing a dead person a "happy birthday" is a pretty strange thing to do, and doing so as a way of displaying one's good taste and mastery of the calendar is one of many strange behaviors that the internet seems to exacerbate. I don't like it, particularly. But were it not for this custom, I'd never have heard of Dr. Seuss's The Seven Lady Godivas, so, you know, yay internet.
I posted my own brush with Seuss here.
