That last page is just wonderful. Makes me think of the JUSTICE LEAGUE episode "Comfort and Joy," where Ma and Pa Kent are regaling a visiting-for-the-holidays J'onn with tales of how they had to wrap wee Clark's presents with lead-foil paper to keep him from peeking. Clark's eyes narrow, and he says, suspiciously, "You mean Santa had to wrap them."

This is close enough to Grant Morrison and Dan Mora's take on superhero Santa that it kinda feels like a crossover...
