It really is quite creepy. Eee. You ever read Albert Camus? He'd have something to say about Gaiman's santa, much in the style of Sisyphus - ie, St Nick would have to enjoy it in some respect, as we all must give meaning to our lives somehow, even to the most pointless of tasks.

Ah, look at me destroy fun literature. Oooh, makes me feel all warm and pretentious. :p
