Dr. Katz is a divorced psychiatrist who lives with his son, Ben. While trying to help his patients (famous and not famous) with their traumas, paranoias, conflicts and problems, Dr. Katz also handles his own problems. His son Ben is all grown up but still don't know what to do with his life. His hobby is to waste Laura's (Dr. Katz's sarcastic receptionist) time with cheesy pick up lines and useless ideas and inventions. Dr. Katz also has a Cheers like bar called Jacky's 33 where he usually hangs out on his spare time, mostly chatting with his friends Julie and Stan. Julie is the bartender, who is studying to become a physical therapist and for whom Dr. Katz has a crush on. Dr. Katz, Professional Therapist was a cartoon based on Jonathan Katz's personal life. Originally running on Comedy Central, the show aired for 5 and a half seasons, and helped put Comedy Central on the map, along with fellow cartoon hit South Park. Halfway through its sixth season, the network cancelled.
Katz is called to testify as an expert witness in the trial of a boy named Roger who broke into an elderly couple's home, tied them up, then wrote with permanent markers all over their walls. The issue is whether he's mentally competent to stand trial, and it's up to Katz to determine that. Ben wants to know why Katz is doing this, instead of the ""charlatans"" they usually get (""They were busy,"" Katz says), but when he learns that it pays $400 an hour, he encourages this new pursuit of his dad's. Eventually, Katz finds Roger not competent to stand trial.
It's Thanksgiving, and something big happening: Katz's ex-wife Roz is coming for dinner
Tragedy strikes when the family TV dies (""Maybe you should give it mouth-to-mouth,"" offers Katz). Ben, of course, is most stricken by this event, unable to live even a day without it. He also can't wait for Katz to get home so they can go buy one together; instead, he has a 72-inch TV delivered to the house.
Ben thinks Katz is drinking too much ("Take the mask off for one minute"), which of course he is not. As usual, Ben goes way overboard, mentioning a TV program he plans to watch: "The Drinky Guy Who's Drunk All the Time, and His Name is My Dad" ("Drinky the Drunk Guy" is Katz's suggestion for a similar program). Ben calls Laura to check on his dad, and she tells him not to let his own hypochondria extend to his father. He attempts an intervention, guided by a pamphlet called "Why is Daddy Actin'Funny?" but it's a bad time for Katz, who is busy reading "The Foot Bridges of Madison County." So Ben vows to try the intervention at a more convenient time.
Katz goes on a couple dates while Ben has no plans other than taking a shower, feeling clean, and then maybe shaving all his body hair. Katz expresses concern to Julie and Stanley about Ben's sex drive and social life. Ben looks up a few old girl friends and winds up with a date with one from fourth grade. He also wants to go into hydroponic farming "because it's fun." We see Grace the cleaning lady briefly as Katz mentions that sometimes Ben rubs up against her. (The only other time we've seen Grace was in #103.) Also, we hear the information operator on the phone; her voice is unaccredited, but it sounds a little like Laura.

Ben wakes Katz up in the middle of the night, claiming to hear a noise. Katz hears it too, and they both think they're being burglarized. After first trying to scare off the burglar (""I'm sure glad they haven't outlawed semi-automatic weapons in the city yet!""), they give up (""Help yourself, take whatever you want, just lock up when you're done""). Turns out the burglar doesn't get in, but Katz and Ben over-react -- oddly, this time it's Katz who over-reacts more. They get new locks and bars on the windows, and Ben wants a hamster. Katz tells Julie and Stan that a home is burglarized every 15 minutes, and that he can't believe he called 911 and was told he had the wrong number. (Stan: ""Did you dial N-I-N-E-one-one?"" Katz: ""OK, you win, you're the stupidest guy in the bar."") Katz suggests a lower peephole, in case the burglar is a midget. Why? Because every horror movie he's seen has an evil midget in it. (Movies mentioned: ""Midget Killers,"" ""I'm Small and You're Dead,"" ""Too Small to Let

Katz decides to keep a bowl of fruit at the office, but it goes rotten pretty fast. He talks about it at the bar, and Stanley pronounces ""fructose"" as ""fruck-tose."" Meanwhile, Ben considers a variety of career options, after being told by his dad that he's ""pissing his life away"". He tries cake decorating and makes a cake made purely of frosting; takes up roller-skating; considers being a truck driver; and asks if there's a job for what he used to do as a kid: put on a pair of dad's pants, pull them way over his head, and stumble around the house.
Katz seems to be losing energy and is sleeping later in the morning. He wonders if he's feverish, but in fact, he feels a little cold.

Katz puts his back out while putting on his shoes, and Ben, as usual, is a wealth of help. He eventually becomes Katz's primary care-giver, though, driving him to work, carrying him into the office, and turning him over to Laura, warning her that he's heavily doped up on medication.
