Feral House has a great new book coming out about Funnyman, an unusual and short-lived comic book series created by Superman's Jerry Siegel and Joe Shuster.
Funnyman was a clown-like superhero who used gags, pranks and Yiddishisms to defeat his humor-deficient enemies. He was a dead ringer for Danny Kaye, one of my favorite comedians. The comic book was a total flop. It ran for six issues and went out of business. Siegel and Shuster tried to keep it going as a newspaper strip, but gave up after a year. The team never worked together again. (Joe Shuster went on to illustrate seedy little bondage booklets, barely scratching out a living. You can read all about it in Craig Yoe's book, Secret Identity: The Fetish Art of Superman's Co-creator Joe Shuster.)
