Mark Evanier has not only attended every single San Diego Comic-con since its inception, he's been a vital part of that famous gathering (which is on sabbatical this year)—moderating panels with pals like MAD cartoonist Sergio Aragones, interviewing icons like Ray Bradbury, and more. Mark's writing career has taken him from comic books to sitcoms and beyond (if you don't have his book Jack Kirby: King of Comics, you should). Leonard and Jessie are longtime friends and know what a great raconteur he is—as this episode will confirm.
