Once again spiny your superior grey cells may have defeated mine in this Andy G celebrity death match, but what the heck, I'll give it a try.
In one episode, Barney is trying to explain the Emancipation Proclomation. I believe he explained it something like this, " A long time ago there were these people who needed emancipatin, so they issued this proclomation, and that's why it's called the Emancipation Proclomation."
Or their was one episode where Opie killed a mother bird and Andy forced him to raise the 3 chicks to learn responsibility for his actions (Winkin, Blinkin and Nod). At the end Opie wants to keep them caged and ole Andy pulls a Morgan Freeman line out of The Shawshank Redemption, some things are just to beautiful to keep locked up, you have to set them free to see their true beauty. Then he sets them free and they promptly take their place in one Mayberry tree and begin to sing their hearts away. Opie makes the comment that the cage looks empty, but Andy never the one to let a lesson slip away, promptly reminds him of how full the trees are.
Now I'm tired, did I even get close?
