Viking? I'll take that as a challange!

I've just come back from a yakiniku all-you-can-eat buffet. If you know me, I take that literary. After all, it's all-you-CAN-eat buffet, not a sissy all-you-want-to-eat buffet. Last one who throws up looses. As if that wasn't enough, buffets are for some strange reason called "Viking" in Japan. Probably in the sense of "Real men are big, hairy and can eat half their body weight in meat. You're not a girly man, are you?". Girly man? Oh, it's on...
