Hi, since I´m too stupid to upload photos, here´s a link that shows Santa Claus on a modern German submarine in Kiel. It´s no joke, the text says that a German skipper arrived at port as Santa Clause in order to visit 60 children (probably some charity event). As you probably know, Germany´s submarine fleet has it´s homebase in Eckernförde, near Kiel (you can visit U-995 and the "Marine-Ehrenmal" there, too.
