Pizza and Movie Night
If you want to get your entire family in on the action, plan a fun pizza and movie night on the condition that the whole house gets a once-over. If you have young kids, pair them up as a team and tell them they're competing with Mom and Dad. The key here is to get your spouse on board, too. Whoever the non-cleaner is may need a little coaxing, but having one parent not participating sends a confusing message to the kids. Make sure Mommy or Daddy plays along so your children understand the work/reward aspect of the game.
