Mrs. Bowen: I have green fingers, Mr. Saunders, did you know that? Everything I plant grows. Even...me!
Saunders: You know, from little acorns mighty oaks grow. That's a fact. But do you know what grows from an old lady's fingers? Hmm? Old ladies!
The exterior of the house used in this episode is the same house as used in the episode "Dark Boy" from earlier this season.
This episode is based on the short story "Green Fingers" by R.C. Cook.
