Through the second and third seasons, in the theme song, as the daughters appear, Cindy has her hand on her neck and quickly removes it.
Peter: I Greg doesn't have to finish high school, they why should I have to finish junior high?

Greg and Don Drysdale shared something in common besides their love for baseball, they also share the same shirt number. Drysdale's number was 53, and when Greg is in his room looking at the mirror, you can see on the back, that the number on his shirt is 53. I knew what number Drysdale's was, because I looked it up on Wikipedia.
Beginning with this season, Marcia began having long hair, having removed her pigtails from the previous season, in the nine-square grid and in the plotting scenes and throughout the remainder of the series.
This is the first episode where Marcia, Jan and Cindy are seen performing ballet.
Hall of Famer Don Drysdale had just retired the previous year.
This was the first episode that aired where the Brady Bunch Kids sing the theme song.
This is the only episode where we see Greg cry. The tears flow toward the end of the show after the big-headed, arrogant, overconfident 14-year-old Greg (who has designs on being a star Major League pitcher throughout the show) is thoroughly humbled and embarassed in a 12-run, no-out, first-inning shellacking in his Pony League game. Of course, Peter and Bobby (who find the embarassment worth a few laughs) don't make things any easier.
