Re: using the wrong bathroom...I used to be a Cub Scout leader and when we went on field trips, I used to take the boys into the mens room on purpose (I'd never let the boys go alone...too much temptation for them to get in trouble!). I'd stand in the doorway and yell "Woman incoming!" I've never cleared a room so quickly! LOL
