The opening credits for the first seven seasons begins with a shot of the back of "Radar O'Reilly's" head. After Gary Burghoff left the series the shot was removed, even though it was not a front shot of Burghoff.
In preparation for his departure, Gary Burghoff is listed at the end of the opening credits as "Also Starring...", instead of his usual credit listing.
The title is from the phrase "too many cooks spoil the broth."
