3. Themed Valentine's Day Surprises

Does your Valentine have a favorite theme? Maybe he or she loves (ahem) Glee, or My Fair Lady, or, I don't know, Rocky Horror Picture Show. The point is, pick one of your Valentine's favorite things, and give him or her themed presents and surprises – or throw a themed party. Just make sure not to give them any inappropriate gifts in mixed company. That's never a good idea.
