According to urban legend there was once a department store in Japan that, shortly after the war, displayed a smiling crucified Santa at Christmas, mistakenly believing that that was how Santa was supposed to be displayed. In different versions of the legend the crucified Santa was either a small miniature or an 'enormous effigy'. There's no evidence that the Japanese crucified Santa ever existed. But people here in America have, of course, deliberately stuck Santas up on crosses. Here's an article that refers to a guy who delighted his neighbors back in 2002 by placing a crucified Santa in his front yard:
A unique holiday display in Boise has prompted mixed reactions from neighbors and passersby. Residents of a home in the 6300 block of Ustick Road have erected a cross with a full-size, stuffed Santa Claus attached. Chili Ciluaga got the idea to build the crucified Santa in his front yard while watching a TV commercial. He said the display conveys the message that the holiday season has become over-commercialized.
