It starts with Clark Kent at work.

The Daily Planet received a letter from a little boy asking if Santa was the real deal, so naturally good ol’ Superman wants to spread the holiday cheer. He decides to visit the little boy.

so there he is, headed over to the little boys house with his awesome sleigh when he runs into the Batman ofcourse.

 

Batman: … Dude, what are you doing?

So Superman tells him about the little boy and Santa and Christmas magic. 

NATURALLY, Batman starts picking on Superman (and talks about his parents again).

the Man of Steel succumbs to the Dark Knight’s teasing, gets rid of the santa gear, and decides to call it a night.

But on the way home, the Big Blue Boyscout can’t help it. He thinks to himself, “Aww hell, I might as well, just go see how the kid is doing.”

So he flies over to the little boys house and OF COURSE:
 

 THE END!
