With apologies to Bob Newhart and others, my favorite TV shrink will always be Dr. Katz, Professional Therapist. A lot of the best comics of our era tried out their routines—and worked out their issues—on Dr. Katz's couch, and the effect was certainly therapeutic for viewers like me. The animated series ran from 1995-1999 and marks its 20th birthday this year with a live performance at SF Sketchfest. I spoke with co-creator and star Jonathan Katz about the show, his life and career. Including: improv with H. Jon Benjamin and Laura Silverman; hustling ping-pong with David Mamet; how not to pitch a project; ripping it up on a mobility scooter.
