Fuck Superman.

[Pun]

The bigger question is why is Batman dressed up like Santa Claus?

[Stu]

It's from the Infinite Christmas (FUCK THE PC TITLE CHANGE) special, and Elseworlds story where a kid writes to the Daily Planet asking if Santa exists, so Supes dresses up as him to go visit the kid, only for Batman to talk him out of it because he's got better things to do with his time. Superman agrees, but decides to go deliver some presents anyway, only to find Batman filling the role as Bat-Santa.
You should read Superman #666, where just because he's dreaming, Supermand decides to go on a world destroying rampage, which includes killing all his friends and family, all his enemies (including Lex Luthor by spitting a superloogey through his head) and just generally telling things like they are.
