Chocolate. Only, they don't have 1lb. boxes of chocolates except on Valentines Day. But chocolate chips come in 16oz. bags. That's awesome. I just need some flowers, to complete the whole romantic vibe. Wait, my wife doesn't really like flowers. Flower, flour. I could buy her a pound of flour and combine it with her chocolate chips and make her some cookies. I am great at this!
UPDATE: Well, things didn't go so well. Apparently McDonald's is not a good anniversary restaurant. To top it off, I accidentally drank the beer that I was going to give my wife, and remembered that I can't bake. In the end, I learned that giving your wife a $16 Gift card to Wal-Mart and asking her to make her own cookies will earn you a romantic night... for one, at the local emergency room.
