I am reading the book about the Simpsons and I don't understand this line:
'Putting the Spring in Springfield.'
The line is the title of chapter from the book. I suppose the line 'put the spring' means breathing life or revival or something like that. Regarding the meaning of the word 'spring', it could mean grow out, put out, bubble up or occur. I am not sure whether I'm right or not, so that's why I'm here. Does it mean breathing life to Springfield? Can anyone please explain to me what does it mean?
Also I did some research on it, and I think this line may be related to the song "We put the spring in Springfield" from the Simpsons.
Link to the song on YouTube.
