Having spent the first half of his career toiling away in relative obscurity, it’s understandable that Jon Hamm has made a habit out of making the most his downtime while MAD MEN’s on hiatus. Next up, in his impressive string of guest spots that include recent appearances on 30 ROCK, the Emmys, Rob Corddry’s CHILDREN’S HOSPITAL, Joshua Malina’s BACKWASH and CONAN, is a right of passage for any actor of his acclaim: THE SIMPSONS.
