“The professor and Mary Ann,”
My favorite GI story is about that line. Originally it was “and the rest” an Wells and Johnson’s names were not in the opening credits, only at the end of the show. Bob Denver hated that, and without telling the other actors went to the producers and asked that they change the song and opening credits to include them. He was initially told it was too expensive. He then told them that his contract allowed him to decide where his credit would go. If they didn’t include Wells and Johnson in the opening, they would have to move his credit to the end of the show with theirs. The producers finally agreed.
Denver never told anyone else that he did that. Wells said she only heard about it decades later when someone doing a book heard it from one of the producers and told her.
....and the rest.
