Do you guys have any 'weird' family or personal traditions for Christmas?
Family wise we have this ridiculous glass pickle ornament that *must* be hung on the tree every year. My grandmother insists that it's a German custom. So far as I can discover, it is not. It's a strange marketing ploy that it's a German tradition, but not an actual tradition. None the less, that ornament is there every year. It's a running family joke.
Personally, my Christmas is not complete until I've watched Alien (and sometimes Aliens). Because nothing says joy to the world like a chest bursting alien life form. :)
