Help me remember this quote

It was a funny quote attempting to define the pledge of allegiance. A very loose paraphrase: ‘an oath and plea to god to look over and save the country from harm, usually exacted upon school children.’ Now, I want to find the original because I remember it being way funnier than that, but I can’t source it. I’ve looked at the usual suspects: Twain, Mencken, Wilde, the Devil’s Dictionary, Sinclair Lewis, and George Carlin, but I fail. I’m either not looking in the right place or just being dumb. I swear I read it on a Wiki quote page for one of those esteemed gentlemen but alas, I’m lost.

Does anyone remember the quote I’m thinking about?
