Rules for children cleaning their bedroom together

Rule the 1st:
There shall be no agreement, under any circumstances, as to the disposition of any object.

Rule the 2nd:
There shall be much exclamation over every object unearthed from the bed.  Comments such as: "Mom's been looking everywhere for this!" and "I wondered what that smell was!" are to be deployed to keep parents alert.

Rule the 3rd:
When working under an adult-imposed deadline care must be taken not to start too early, lest the adult in question relax.

Rule the 4th:
If the threat of progress raises its head play "This Isn't Mine:"

• The first child should select an item.  Something hard and aerodynamic is preferred.
• State, loudly and clearly, "THIS ISN'T MINE," and throw the item on the second child's bed.
• The second child then states, "THIS ISN'T MINE," and returns the volley.
• Scoring is as follows:
• 1 point for each successful landing in enemy territory.
• 3 points for an interception
• 5 points for landing the item somewhere that requires a hunt (under the bed, etc.)
• 10 points for chipping a wall
• 10 points to each player if a parent confiscates the object
• 30 points to the first child who takes a direct strike to the head (signal this point by screaming "OW" and bursting into tears).  10 bonus points for making your sibling cry before a parent gets to the room.
