It was computer animated in a unrefined eventually well recognizable style known as Squigglevision, inside which a lot souls & animate objects come colored & st& constantly squiggling outlines, spell entirely more inanimate objects come however and commonly gray in color.

A indicate focused around a title character, Dr. Jonathan Katz, who is voiced by, & visually according to, a comedian of the same title. Dr. Katz was the agency psychoanalyst who had renowned comedians & actors as patients, usually deuce by the episode. A comedians would normally perform poop from either their work when actors would play out colloquial skits.

More characters involved Dr. Katz's boy, Benjamin Katz (H. Jon Benjamin), his secretary, Laura (Laura Silverman), and his two friends: Stanley (Will Le Bow), and the barmaid, Julie, voiced by the show's producer, Julianne Shapiro. Within down the road episodes, Todd (Todd Barry), the videos store clerk, became the common counterpart to Ben.

Apiece indicate would occasionally commence by owning Dr. Katz & Ben waking higher & beginning the plotline divided per deuce. These plots involved cases such as Ben attempting to be the radio personality, believing he's in possession of ESP, and a moral conundrum he suffers after getting the chain-letter. A development one plotlines would occur fragmentedly throughout a episode alongside a segments between Dr. Katz & his guests.

Lot of the indicate's content, particularly dialogue between Katz & Benjamin, was improvised through a run known as "retroscripting", where a undefined outline is developed however the actual dialogue is adlibbed. This style, too when Squigglevision, would reappear around Home Movies, a cartoon that features several members of the Dr. Katz cast & crew. Notable Guests
