Randy Disher

Randy is Captain Stottlemeyer's second-in-command and employed at the San Francisco Police Department. He is usually portrayed as loyal and tenacious, but with a comical lack of insight and given to far-fetched theories, which were a running gag of the series. Aside from his truly ridiculous theories, which often involve defying the very laws of physics (for instance astral projection), he is competent within his own range of abilities.

Another running gag in the series is the rather awkwardly ceremonial way in which he delivers news to Stottlemeyer, asking him to guess what it is or sit down for it; this method mostly annoys others who would like him to get to the point.[2][3] His feelings towards Monk change from the pilot episode of the series. In the pilot, Randy is not only skeptical of Monk, but he seems to find Monk a joke, even calling Monk "the defective detective" to Stottlemeyer. What appears as his jealousy of Monk in the beginning becomes admiration as their relationship develops.

In the book, Mr. Monk and the Blue Flu, Stottlemeyer, in a covert meeting with Monk and Natalie, reveals that Randy has a high clearance and conviction rate. While teaching Monk how to be a Captain and delegate, he tells them how Randy is a people person, who gets people to say things they wouldn't have said otherwise. They aren't high profile or unusual like the cases Monk gets, but it is how Stottlemeyer delegates cases. The implication is that Stottlemeyer is a good captain for matching staff to cases, and Disher, while incapable of solving a weird case, is good at others, which is his gift.

His original name for the pilot was Randy Deacon, as part of the creators' homage to Sherlock Holmes' Lestrade (LEland STottlemeyer and RAndy DEacon). It was changed to Disher for the rest of the series.

In the episode "Mr. Monk Goes to the Dentist", much of the case was solved by Disher. In "Mr. Monk Visits a Farm", Monk feeds Randy, in the latter's sleep, the solution of how Jimmy Belmont killed Randy's uncle.

During the series, Randy loses his entire life savings during a trip to Las Vegas in "Mr. Monk Goes to Vegas", which prompted Monk and Stottlemeyer to come to his rescue, using Monk's abilities to win the money back. He acts as Natalie Teeger's bodyguard in the episode "Mr. Monk and the Election". He helps Monk find clues for the Trudy Monk case by traveling to New York with him in the episode "Mr. Monk Takes Manhattan". Randy is shown to argue regularly with but not-so-secretly be attracted to Sharona Fleming, and he maintains a friendly, professional behavior towards Natalie.

Throughout the series, Randy seems to always harbor crushes on Sharona and Natalie. As well, he writes a personal ad fitting Sharona in the episode "Mr. Monk and the Paperboy", which he unsuccessfully tries to hide from her. In the season 6 episode "Mr. Monk and the Bad Girlfriend", when Natalie tells Randy that she and Monk have news, he guesses that she wants to say she is in love with him, leaving Natalie in a dumbstruck state while Monk delivers their theory that Linda Fusco killed her former partner. Natalie is shown to be rather annoyed by Randy's theory that she is in love with him (bringing it up again when Monk asks Randy if he has any crazy theories about how to break Linda's alibi).

Randy's lack of luck getting dates is so notorious that when he actually does land a girlfriend, in the episode "Mr. Monk and the Employee of the Month", no one believes him. Throughout that episode, he shows the cast a generic picture of a woman. Sharona confirms that it was included with his wallet. They dismiss Randy's claims that his girlfriend is a wallet model named Crystal Smith (when Randy mentions that her first name is Crystal to Sharona, she asks if Crystal's last name is "Glassware", referring to the box of crystal glassware she is seeing in the loading dock). It is revealed to the viewers but not to the characters that Randy was telling the truth.

A few episodes later, in "Mr. Monk Gets Cabin Fever", he dates a Chinese woman named Hayley, only for her to turn out to be part of a Triad hit crew sent to eliminate Monk after Monk goes into witness protection for witnessing a gang shooting.

In later seasons, Randy's success with women significantly increases. In "Mr. Monk Falls in Love", he's dating an attractive girl as shown by the opening scene, when he and his date climb into the back of a cab, only to find that their driver is dead, having been stabbed with a hat pin by his previous fare. In "Mr. Monk's 100th Case", Randy is dating Jillian, the actress who plays the reenactment of Kate Kindel's murder in James Novak's documentary. She is described as being used for reenactments on a number of crime shows (as Randy notes that she was bludgeoned to death on Dateline).

In the episode "Mr. Monk and Sharona," Randy and Sharona have a fond reunion. While reminiscing over the cases that they've worked, Sharona apologizes to Randy for the amount of teasing that she gave him; he, in turn, states that he "missed" it. At the end of the episode, Randy picks up Sharona to go to the airport, sharing a kiss as they load her bags. In the series finale, "Mr. Monk and the End," Randy accepts a job as Chief of Police in the town of Summit in Sharona's native New Jersey, stating that he and Sharona are becoming a couple.

Randy is noted to have been born in San Diego.[4] He attended Temple University and lived in Philadelphia briefly, where he was a sergeant in that city's police. This is mentioned in the season 4 episode "Mr. Monk Goes to a Wedding". In Philadelphia, one of Randy's cases was that of Darlene Coolidge, a black widow who murders her husbands. In "Mr. Monk Goes to a Wedding", someone attempts to run Randy down in the parking lot of a hotel where the wedding of Natalie's brother Jonathan is to be held. Monk discovers that Jonathan's new wife, Theresa Scott, is actually Darlene. As Randy was the chief investigator into the death of her husband, he would have recognized her, so Theresa tried to kill him by running over him with a car. Randy suffers multiple broken bones that leave him confined to a wheelchair, but with Stottlemeyer's help he reaches the reception in time to identify Theresa/Darlene, allowing the local police to arrest her.

In the season 5 episode "Mr. Monk and the Leper", Monk and Natalie find a picture of Randy on the wall of Dr. Aaron Polanski's office. Polanski mentions that Randy as a teenager had incredibly bad acne, although when Natalie asks Randy about this later, Randy says that he was undercover and posing as a teenager with acne problems. He attempts to steal that picture later, ending up ripping out a small portion of the wall and knocking off a large number of other photos in the process. He joined the police force three years before the start of the series. In the season 2 episode "Mr. Monk Gets Married", Randy has Monk and Sharona pretend to be married in order to rescue his mother Maria from Dalton Padron, a killer with a very ulterior motive. While at the marriage counseling institute, Maria mentions Randy several times to Monk and Sharona, but they pretend not to know Randy.

Although he denied having an uncle in the season 3 episode, "Mr. Monk Gets Cabin Fever", Randy later is found to have had at least one uncle, Harvey. In the season 5 episode "Mr. Monk Visits a Farm", Randy inherits his uncle's farm after Harvey Disher supposedly commits suicide. Soon after Randy arrives at the farm, he gets a chilling suspicion that a neighboring farmer named Jimmy Belmont (Ricardo Chavira) killed Harvey, and Randy brings Monk in to prove that there has been foul play.
