Saint Patrick's Day is one of those holidays where it's either announced and people get ready and plan festivities far in advance, or civilization as a whole completely forgets about it until it happens. It's probably 'cuz presents aren't involved, am I right.
But SOME people are festive. I can CLAIM I'm being festive because my nice shirt I'm wearing is greenish-olive-ish. And someone photoshopped Goatse to have very bright green, er, innards instead of red. :P
