Check out this open letter to Rudolph:
I'm reminded of a talk I recently heard that explored several facets of postmodernity, one of them being the "hermeneutic of suspicion"--fancy talk for "ironic cynicism." It takes a letter like this to see the cultural subtext of Santa Claus, but it's the sort of letter that trips up people with no sense of irony. Of course, people with no sense of irony reading an ironic letter like this is as entertaining to an ironic cynic as anything else.
If you have no sense of irony, my apologies.
