The Brady Bunch, Season 3

(Mike's high school reunion is coming up, Carol tries to guess who was "Bobo" in his class)

Carol:
I wonder what Bobo could be a nickname for? Let's see, Bernice Sheeran? Bernice? Bobo? (disagrees)

Mike:
(trying to confuse Carol) Sally.

Carol:
Sally? Oh no, how could Bobo stand for Sally?

Mike:
Betty.

Carol:
Betty? Betty! Bobo, Betty, Bobo, yeah.

Mike:
Zelda.

Carol:
(hits Mike with a pillow) Michael Brady, that's terrible! And that's for Sally, (hit) and that is for Betty, (hit) and that is for Zelda! (hit)
