Sometimes it's a fun treat for your child to get to be the "parent" for a little while. One afternoon, make a game out of reversing roles with your kids. It can be their job to remind you of the rules and of using polite behavior, and you can be as good or as challenging a child as you wish. We usually play this game with my daughter pretending to be me and I pretend to be her. It can be an eye-opening experience for both of us to realize how we sound to the other person. And it can be very funny, too.
