Sick of those constant fights over toys, the remote control or who farted? Buy as many $2 rolls of nickels as you have kids, and write one name on each roll. When someone squabbles, no matter who's "at fault," the bickerer loses a coin. At the end of the week, each kid gets to keep the money that's left in his or her roll. The only downside is that you may never know the true identity of the family's secret pooter.
