From the first episode of "The Mary Tyler Moore Show" in 1970.
LOU GRANT: You know, you've got spunk. (pause) I hate spunk.
My gosh I forgot that!
MTM was funny and clever.
The spunk did not always work out.
She seemed genuinely at a loss at the antics of her co workers.
And the episode at the funeral of the clown Chuckles
