It makes me sad when people refer to concepts as coming from a movie/TV adaptation and not the original written source. The phrase comes from It’s a Good Life by Jerome Bixby.
(It reminds me of a national network news story once that covered some concept as being related to Fahrenheit 451, talked about the movie, showed clips from the movie, and never once mentioned that the movie was based on a book. Ray Bradbury would have rolled over in his grave, if he were dead yet. He might have rolled over in his living room.)
