See Jerry Lewis and Herb Edelman in “Cracking Up”
Loved Jerry Lewis comedy. Especially loved his great big "F*** YOU!" to Dean Martin known as "The Nutty Professor."
He skewered Dean Martin's "cool" act mercilessly. He showed what a unlikeable pompous @$$hole could look like when he treated other people as beneath him.
I wonder if Dino recognized himself in that caricature?
