A Valentine's Day party can be lots of fun, but it's hardly a novelty. So try picking a lesser-known holiday or day of note from which to create your dinner party. The sky's really the limit here.
If you choose Groundhog Day, for example, you can serve all brown foods, foods shaped like the furry critter, or plan your evening according to the popular 1993 comedy movie of the same name, dining on dishes referenced in the movie, playing the soundtrack in the background, etc.
And why not even create your own holiday -- or steal someone else's. Throw a party to celebrate Festivus (every Dec. 23), courtesy of Frank Costanza on the TV show "Seinfeld." The Feats of Strength, one of the hallmarks of Festivus, would make for some great after-dinner entertainment!
