Did you know it was Constitution Day? I didn't, either, until just now. And then I decided that if Constitution Day is to be a proper holiday, and not just something Senator Byrd made up, it should have cake.
There! Consider the Constitution celebrated.
Though maybe it'd be better to have cupcakes. We could have different flavors for each amendment! The 19th could be strawberry, because it's related to women, and therefore must be pink.
