Every Boy Does It Once was the 10th episode of Kids World's Adventures of The Brady Bunch.
After Bobby watches a television adaptation of "Cinderella," older stepsisters Marcia and Jan tease him, then Carol asks for his help in sweeping the chimney. Bobby reasons that what he just saw on TV was correct: All stepmothers and stepsisters are evil. So, feeling unloved and unwanted, he decides to run away.
After Bobby and Cindy watch Cinderella on television, Bobby initially believes Cindy in that Bobby's stepmother - Carol - is a loving mother, period, unlike Cinderella's. But Carol asking Bobby to clean out the fireplace, just like Cinderella's stepmother did, makes him start to think otherwise. Carol altering some hand me down clothes for him - which Greg and Peter don't get - and all the older kids taking off for the evening either without saying goodbye or telling him straight to his face that he can't go along makes Bobby not only feel like the brunt of the evil stepmother's actions, but unloved by everyone in the house.
When Alice learns why Bobby is in such a down mood and passes the information along to Carol and Mike, Bobby's parents think the way to make Bobby feel loved is to get him an early birthday present of a bicycle. Words from the bicycle salesman along with further learning that Bobby is planning on running away make Carol and Mike come to a decision on what they really need to do to make Bobby feel cared for, especially by Carol.
Meanwhile, Bobby plans to run away from home, but is caught packing by Peter, and confides in him that he's running away. Peter passes on the information to Greg and Greg to Alice.
