I saw George Lindsey on the Tonight Show back in the 80s. Johnny Carson asked him about Mayberry, and he responded with a poem about how Mayberry was a place that fed the soul. It was all about knowing your neighbors and lending a helping hand, being able to leave your doors unlocked and all that small-town utopia kind of stuff. The poem ended something like this:
Mayberry's the kind of place where you can be yourself,
You can scratch when you get an itch,
But what I love most about Mayberry is
It made ol' Goober rich!
