Is there an episode where Mike Brady goes on a diet.
I used to watch Brady Bunch reruns years ago. Did Carol ask Mike to go on a diet. Or am I thinking of another show.
No body was overweight in the 1970s.
You might be thinking of Season 5, episode 7: "Marcia Gets Creamed"
There is a subplot about Mike and Alice trying to lose weight.
