Backwards Birthday Party Face it, kids love Anarchy.  Throw out all the rules, or better yet, invert them. You'll need a little time to indoctrinate the guests.  "Hi" is "Bye" and "yes" is "no" and it gets confusing fast.   Use the format for a traditional party, with games, food, etc and apply your new rules.  Have the drinks out of a bowl (outside), and eat your pizza out of a glass.  Serve the dessert before the main course, and hang the party decorations upside down.
