Nothing beats John Updike's take on creepy Santa in a New Yorker magazine of several years ago. Tried to find it on the Net but no luck. Talks about hearing the Christmas tree slurping up water in the night. Totally hilarious.
One of my Christmas cards this year has Santa on the couch, saying that his obsessive-compulsive disorder has become worse: He's now checking his list three or four times.
Ha Ha Ha! (or Ho Ho Ho)
