Complete story — includes the ending
When Bobby and Cindy are not invited to Carol's cousin's wedding and instead are asked to stay out of the way of their older siblings' activities, they decide to show how "important" they are by setting a world record for hours spent on a seesaw. They get newspaper coverage for their attempt, which ultimately fails when they fall asleep short of the record. They then learn that they set a record for kids around their age. The older siblings realize the attention-craving Bobby and Cindy indeed have their place in the family and are worthy of respect. In the subplot, the older Bradys are planning for the wedding.
