Uncle Spooky, the blue-faced host of the late-Tuesday-night “Scary Movie” screenings at the Ice Palace, celebrated his birthday on July 16, with a cake with blue icing, laced with edible vampire blood, and a knife sticking out of it, echoing the imagery associated with the featured gory slasher film of the evening, J. Lee Thompson’s “Happy Birthday to Me” (1981), starring Melissa Sue Anderson, of “Little House on the Prairie” fame, and Glenn Ford.
