Dr. Katz, Professional Therapist is on my short list of shows that were good from start to finish. This consistency is due to the show's brilliant comedic cast and the fact that every episode followed the same simple, perfect structure. The show's weekly guest stars are among the most talented and successful stand-up comedians around. Many of them went on to star in popular TV shows and films--people like Dave Chappelle, Ray Romano, Richard Lewis, and Wanda Sykes. There were also noteworthy appearances from now-deceased comedians Rodney Dangerfield and Mitch Hedberg, actors like Winona Ryder and David Duchovny, and award-winning writer David Mamet.

If you're like me, and have trouble picking a favorite season of Dr. Katz, the Complete Series box set is an ideal choice. At a cost ranging from $88 (comedycentral.com, on backorder) to $112 (amazon.com), the set definitely belongs in the "splurge" category, but it's well worth it.

I was unaware of this until recently, but apparently some live stage versions of Dr. Katz: Professional Therapist were performed with the original cast and crew.

Dr. Katz: Professional Therapist was, if you don't know, an animated series that aired on Comedy Central in the late '90s. It starred comedian Johnathan Katz as a therapist to several comedians, who would essentially do their shtick while he would listen and respond. The episodes didn't all take place in Katz's office, it also expanded to his home and personal life to include his son Ben (played by Jon Benjamin) and his receptionist, Laura (played by Laura Silverman).
