Forgotten holidays

So today is Cinco de Mayo. I actually didn't even know this holiday existed until 2001, when one of my co-workers asked me if I was going to any sort of Cinco de Mayo party that weekend (it fell on a Saturday that year, too). I didn't party that year, and I probably won't this year. Though I'm sure many people will be celebrating this little event today, maybe with a mint julep or two.
