Ben is in the newspapers for witnessing a crime. Dr. Katz and Laura both remark that it's odd that he used his real name instead of choosing to remain anonymous. Ben thinks he's on the road to stardom because of this one-time incident, and wants to go to a school to tell his story. However, in the end, it's revealed that he didn't actually see a crime and lied to the reporter: "It was in the heat of the moment and I had to say something." Dr. Katz grounds Ben.
Without consulting him first, Ben agrees to let Dr. Katz's ex-wife sleep in their apartment for a couple days. Meanwhile, Ben searches for an apartment of his own but gives up when he sees how expensive it is.
Dr. Katz buys a pair of glasses. Everyone thinks they look awkward. Ben tries to have some fun with what he believes is Katz getting older by playing some pranks on him, including hiding his cell phone and removing all the chairs from the kitchen.
Laura calls Dr. Katz's apartment to say she won't be into work, using the lame excuses that she needs to get her watch fixed and do holiday shopping. Ben wonders if she's unhappy at the office and that's why she's calling in sick; Dr. Katz agrees and upgrades her position from "receptionist" to "administrative assistant". Since that doesn't seem to do anything for her, Katz throws an office Christmas party, though because of the size of his business, it will only be the two of them. When Laura arrives at the party, she almost immediately announces she has to go (...
Ben gets into Dr. Katz's medical books and convinces himself he has all sorts of medical illnesses including, of all things, Sudden Infant Death Syndrome (S.I.D.S.). Meanwhile, Dr. Katz is afraid of a bee that's made its way into his office. Laura plays on his fear and refuses to kill the bee at his request. Also, Patient Dom Irrera leaves a love proclamation song on Dr. Katz's answering machine.
Dr. Katz is suspicious that Laura is stealing office sticky notes. Meanwhile, Ben essentially stalks an attractive new tenant in the apartment building, until he gives up because she called him "fatty".
Dr. Katz gets the urge to build a wood shelf for the wall. Ben agrees to get the necessary supplies, but causes problems when he breaks a nail gun and therefore can't return it at the hardware store. In the end, they build a shelf, but it's less than satisfactory, so they plan to put pamphlets on it.
Ben runs into a prostitute on the street. He doesn't take advantage her services, but after a conversation with her, he realizes that many people need help, and wants to be the one to provide it. He begins to make Dr. Katz and Laura feel guilty about themselves, that they're not out on the streets "making a difference", like he is. After a week, Ben gives up, especially after he unknowingly chides a friend of Katz's to improve her life, as he assumed she was a prostitute.
Dr. Katz is asked to give an adult education lecture. Katz chooses to discuss a theory of his: A person gets temporarily smarter whenever they experience physical pain or emotional distress. Ben tries to inflict some pain on himself so he can feel smarter, but fails. At the lecture, Ben jumps his cues to laugh at Dr. Katz's opening jokes, throwing Katz for a loop.
Ben is convinced he has ESP after watching a program about it on TV, especially after a couple of lucky guesses. He warns Dr. Katz to stay away from the bar, though Katz disregards that and nothing bad happens to him.
