I thought Variety's
"100 Best Comedy Movies of All Time" was pretty well done, but what I liked best about it was the way it inspired me to write one of my unwritten books. Look:

To my mind, this still from the movie establishes a proposition I've long been aware of: Zeppo was the funniest Marx Brother. For the uninitiated: Zeppo is second from the left.
Now, for those of you who don't want to read anything written by A.I., it's time to leave. Here's the prompt I took to Grok: "Is it true that in the opinion of those whose opinion counts most Zeppo was the funniest Marx Brother?"
The answer is yes.
First, Groucho said it, repeatedly. Grok writes: "He described Zeppo as having the best natural comic timing and delivery in real life, a dry, deadpan wit that killed in a room, but that Zeppo simply didn’t care enough about performing to push himself forward on screen. Groucho claimed Zeppo could have been the breakout star if he’d wanted it."
Then there was George S. Kaufman, co-writer of "The Cocoanuts" and "Animal Crackers," who "reportedly said Zeppo was the funniest of the brothers in rehearsals and in person." Other authorities who said the same thing included Steve Allen, Woody Allen, and Billy Crystal.
So Zeppo was given the “straight man/romantic lead” role until after "Duck Soup" he quit movies altogether and "became a successful theatrical agent and inventor (he held patents related to the cardiac clamp used in open-heart surgery)."
I was motivated to say: "If the other brothers saw him as the funniest, they had something to strive to excel. Zeppo was maximizing the comedy by performing that role and he didn't have the motivation to excel anyone. He was secure."
Skimming Grok's somewhat lengthy mirroring of what I'd just said, I got a new idea: "I want to expand this into a larger life lesson and write a self-help book — in the manner of 'Let Them' — that would be titled 'Be the Zeppo.'"
1. By "write a self-help book," I meant write a blog post that would earn the tag
"Unwritten Books," that is, the blog post you are reading now.
2. Of course, Grok immediately outlined this book for me, replete with subtitle options — like "The Power of Radical Non-Competition" — and 10 chapters — including "The 'Anything Further, Father?' Principle/One perfectly timed sentence beats a ten-minute monologue. The power of strategic silence."

Here's Mel Robbins, the author of "The Let Them Theory," quickly explaining the whole book to Bill Maher.
