We have "Team ____ Rules " The ___ is our last name. Whenever anyone breaks a rule, anyone else can make a loud siren noise and call "TEAM ___ VIOLATION!" and enforce a penalty. The penalties mostly result in an immediate correction (for shoes in the middle of the floor, door left open etc) or an apology (using a rude tone or saying something inappropriate). Occasionally someone gets sent to the "penalty box" for 2 minutes. Penalty box violations include being told the same thing more than once, bad table manners, repeated misconduct or anything I deem too annoying!

I find it hysterical when my 6 year old puts my DH in the penalty box for being told the same thing 2x!
