It may just be Joss in cryptic crossword mode and a whole bunch of numbered shirts but it does make me wonder if there won't be some Norse themed villiany going on. I mean it's been noted that "muppety Odin" doesn't sound like Buffy word play but I'm not sure it sounds like Xander either unless Odin has a comic book (and his nose comes off in it). If they'd met a giant felt one-eyed viking that would be different. And everyone in the comic seems to know what a thricewise is as if they were as common as vampires now.
