The Brady Bunch
You Can't Win Them All
S4 E22:
Cindy and Bobby have the chance to compete on a televised kids quiz show if they score high enough on a written test. Cindy does everything she can to prepare for the test, while Bobby is over-confident that he can pass without putting forth effort. The studying pays off and Cindy is chosen, but Bobby fails to make the grade and wallows in his misery. Cindys new star status goes to her head and the family tries to deal with her inflated ego.
