This week, we're happy to welcome back friend of the show Jon Morris to talk about his new book, The League of Regrettable Sidekicks! We talk once again about what constitutes a character being "regrettable," the worst Robin, a sidekick that did all the work, the Joker's pre-Harley sidekick, why one notable sidekick is missing, and much more! Plus, a listener question that honors the memory of Stan Lee.
