I remember watching this show late at night with my college roommates and laughing hysterically. Over the past few years, I have been looking for it. I was happy with the first two seasons coming out of DVD and caught a few episodes on Comedy Central "On Demand" through my cable. I was not disappointed. It is still hilarious. It looked to be in jeopardy of being shelved, but thankfully the full-set is coming.
For anyone wondering, the animation is crude, bordering on annoying. But that isn't the selling point. It could be a radio show and it would be hilarious. About 1/2 of the show takes place in Dr. Katz's office as he has therapy sessions with well known stand-up comedians. Most of it is them doing some of their stand-up material and Dr. Katz reacting. This is the most hit or miss part of the show for me. 75% of the comedians are funny. Big names too. Ray Romano, Dave Chappelle, Jon Stewart, Wanda Sykes, Sarah Silverman, etc. The part of the show that never missed for me was the storyline surrounding Ben Katz. Perhaps my favorite character of all time on television. He never misses. He makes me laugh every episode. His interactions with Dr.l Katz, Laura (the receptionist), and anyone else he encounters are very funny.
