Dr. Nick

Dr. Nicholas Riviera (usually referred to as simply Dr. Nick) is a recurring fictional character in the American animated sitcom The Simpsons. He is voiced by Hank Azaria and first appeared in the episode "Bart Gets Hit by a Car." Dr. Nick is an inept quack physician, and a satire of incompetent medical professionals. Upon entering a scene, Dr. Nick's catchphrase is "Hi, everybody!" with the characters present immediately responding (often in chorus) "Hi, Dr. Nick!"

Role in The Simpsons
Dr. Nick has a medical degree from "Hollywood Upstairs Medical College," in the 1970s, where he apparently spent much of his time using his ability to acquire prescription drugs to impress women. Thus far, none of the patients he has swindled, maimed, or given useless or dangerous medical advice seems to have sued him—although a few have come after him in person. For example, in "Homer's Triple Bypass," a large angry man grabs him, and Riviera says "Well if it isn't my old friend Mr. McGregg—with a leg for an arm and an arm for a leg"; the man literally has an arm where a leg should be and a leg where an arm should be, and it is implied that this is Riviera's fault. Riviera is a stereotype of shady doctors who perform medical procedures for money with little or no regard for medical ethics, or their patients' well-being. His motto is, You've tried the best, now try the rest! In "The Girl Who Slept Too Little," he is seen digging up corpses in the graveyard for body parts, presumably to use in operations on patients. In the same episode he tells Lisa Simpson, "You have a check-up on Thursday!" to which she replies, "We don't go to you anymore; we have a better doctor!" and receives a congratulations from him. In "Treehouse of Horror IX," he injects himself with anesthetic after punching Homer in the face in order to knock him out before performing a hair transplant on him, using a pizza cutter.

In the episode "Much Apu About Nothing," he is seen taking a citizenship test, implying that prior to this he was not a citizen of the United States. Though his origin remains unconfirmed, Dr. Nick has a notable Argentine accent in the Spanish-language dubs. In the episode "Margical History Tour," the sequence set in 18th-century Vienna has Dr. Nick saying "Guten Tag, everybody!"

The degrees in his office read "Mayo Clinic Correspondence School," "Club Med School," "Female Body Inspector," and "I went to medical school for four years and all I got was this lousy diploma." He is a member of Sigma Chi fraternity. He frequently appears on infomercials, pitching all sorts of bizarre medical offers or endorsing dubious devices, and has often turned his operations into TV spectacles. He is also shown as an inventor/huckster (in the style of Ron Popeil) on the television show I Can't Believe They Invented It!, with products such as the "Juice Loosener" in "Marge in Chains," an inefficient juicer made in Japan, which ultimately causes an influenza epidemic in Springfield (due to one of the workers at the factory having the disease, but still going to work, thus spreading his germs through the packaging).

Dr. Nick has operated on the Simpson family a couple of times when they cannot afford their regular doctor, Dr. Hibbert, notably when Homer needed a heart bypass. Lisa Simpson attended the live audience for the operation and saved the day by guiding the obviously clueless Dr. Riviera through the operation. He also worked with Dr. Hibbert as an anesthesiologist during Bart's appendectomy (in 'Round Springfield) but was of little help as he accidentally anesthetized himself instead. In the episode "King-Size Homer," he gives advice to Homer and Bart on gaining weight, in order to put Homer on disability from Hyper Obesity. It is revealed in the episode "Homer's Triple Bypass" that his phone number is 1-600-DOCTORB, explaining that: "The B is for Bargain!" His catchphrase is "Hi everybody!" except in The Simpsons Movie, in which he was seemingly killed with a large shard of glass, saying, "Bye, everybody... ugh." However, he has survived and made a few appearances since.

Character
The design of Dr. Nick is modeled physically on Gábor Csupó, the co-founder of Klasky Csupo animation studios (which animated the series for its first three seasons and The Tracey Ullman Show shorts). The animators mistakenly believed that Hank Azaria was impersonating Csupó, when in fact he was doing a bad impression of Ricky Ricardo from the TV series I Love Lucy.

In The Simpsons Movie, Riviera is impaled by a large shard of glass that breaks and falls off the enormous dome covering Springfield, saying "Bye, everybody!" before he faints. Executive producers James L. Brooks and Al Jean confirmed that the character was not dead, but he just fainted, and he would be "brought back to life à la Dr. Marvin Monroe." Riviera is seen alive and well in further episodes after the movie.

The name "Dr. Nick" may be inspired by Dr. George Nichopoulos. In 1967, Elvis Presley came under the primary care of Dr. George Nichopoulos, who was well-known to celebrities. Then, Elvis was 32 and weighed 163 pounds (350 pounds when he died at age 42). His only known medical ailment was slightly high blood pressure, presumably due to his high-fat diet. Doctor Nick, as Nichopoulos was called, stayed as Elvis’s personal physician till the end and was present at the death scene, as well as during the autopsy. Evidence showed that during the seven and a half months preceding Elvis’s death—from January 1, 1977, to August 16, 1977—Doctor Nick wrote prescriptions for Elvis for at least 8,805 pills, tablets, vials, and injectables. Going back to January 1975, the count was 19,012. The drugs included uppers, downers, and powerful painkillers such as Dilaudid, Quaalude, Percodan, Demerol, and Cocaine Hydrochloride in quantities more appropriate for those terminally ill with cancer.

Reception
IGN placed Dr. Nick 23rd on its list of the "Top 25 Simpsons Peripheral Characters." The character was listed in Entertainment Weekly "30 Great TV Doctors and Nurses" and in Philadelphia Magazine "10 Best Doctors on Television."

In a tongue-in-cheek analysis, the Canadian Medical Association Journal (CMAJ) compared the services of Riviera and Dr. Hibbert. It concluded that Riviera is a better role model for physicians, whereas Hibbert, although praised for his sense of humor and quality of care, is a paternalistic and wasteful physician, unlike Riviera, who strives to cut costs, does his best to avoid the coroner and pleases his patients by giving them what they want, disproving Marge Simpson's claim that he is not a doctor at all.
