Funny, I just re-watched all of Dr. Katz on YouTube. Also, Audible did an audio revival of Dr. Katz a few years ago. There are a criminally low number of episodes and they’re all shorter than a Comedy Central episode, but they’re still very funny.
There’s also a live “episode” of Dr. Katz with Jonathan Katz, H. Jon Benjamin, Laura Silverman and a whole lot of comedians on YouTube which I highly recommend.
