''The Nutty Professor'' is a 1963 comedy, starring JerryLewis as an AbsentMindedProfessor who, after being bullied and taunted, invents a [[FantasticDrug serum]] that turns him into an [[TheCasanova incredibly handsome, strong and popular]] man named Buddy Love, his new personality gives him the confidence to pursue one of his students, Stella [[PunnyName Purdy]].

The film was remade in 1996, starring Creator/EddieMurphy, Creator/JadaPinkettSmith, [[RuleOfThree and Eddie Murphy,]] and co-starring [[UncannyFamilyResemblance Eddie Murphy,]] [[ActingForTwo Eddie Murphy,]] [[OverlyLongGag and Eddie Murphy.]] The success of the remake led to a sequel, with JanetJackson amid the various Eddie Murphys.

!!These films provide examples of:

[[folder:In General]]
* AbsentMindedProfessor
* AscendedExtra: Sherman's parents in the remake. The original film, they only appear twice, the first time shown as a [[HenpeckedHusband henpecked guy and his mercilessly henpecking wife]], and the second at the end where [[spoiler:they come to sell the serum to all the kids in school]]. In the remake, they appear far more often, and get along quite well with each other.
*** The sequel of the Eddie Murphy version was actually called ''The Klumps'', making Eddie Murphy's scenes with one actress and several of his own characters into the core of the film.
* AnAesop: BeYourself. Don't try to be someone else to win others' affections.
* BowtiesAreCool: Julius in the original, Sherman in the remake.
* TheCasanova: Buddy Love.
* JekyllAndHyde
** HydePlaysJekyll
* LoveMakesYouCrazy: Why Buddy is left unchecked for way too long.
* MeaningfulName: Stella Purdy in the 1963 film, Carla Purty in the 1996 film -- attractive female students whose surnames sound like the Southern pronunciation of the word "pretty".
* MyGodWhatHaveIDone: Kelp's reaction when [[spoiler: his parents have discovered, duplicated, patented and are selling his Buddy Love formula to the masses.]]
* SexierAlterEgo - In both versions, the titular professor invents a way to change him from a nerdy looking fellow in the original film (and a rather overweight guy in the remake) into a smooth ladies man.
* SplitPersonalityTakeover: Buddy's plan in the late game.
* TakeThat: Eddie Murphy's Buddy Love sent up the negative traits of his own persona during his cold streak at the box office in the early 90s, something that did not go unnoticed by critics.
** Jerry Lewis' Buddy Love has been interpreted as a parody of DeanMartin, Lewis' old show business partner, although Lewis has repeatedly denied this.
** And Dave Chapelle's character is an enormous take that to UncleTomfoolery and hacky stand up comedy in general.

[[folder:''The Nutty Professor'' (1963)]]
* BadassBookworm: As Buddy Love, Kelp uses his knowledge of chemistry to mix up an Alaskan Polar Bear heater, which in this movie is so strong it caused the Bartender to freeze in one sip.
* DoNotSpoilThisEnding: Played with. Trailers for the movie were fine with audiences spoiling the beginning ''and'' ending, but the middle of the movie, which revealed the transformation, was ordered to not be revealed.

[[folder:''The Nutty Professor'' (1996)]]
* {{Acrofatic}}: During his exercising montage, Sherman gains a [[TruthInTelevision realistic degree of agility]].
* AlliterativeName: Harlan Hartley.
* AmazinglyEmbarrassingParents: The Klumps when Sherman brings Carla over. They talk openly about sex, bodily functions, marriage, and other embarrassing topics, so much so that Sherman tries to slit his wrists with a butter knife.
* AsHimself: Montell Jordan.
* ArtisticLicense: Somatotypes. There are three main somatotypes which people can be classified in, and Sherman quite accurately describes one (Endomorph) while explaining why he was dieting to his parents in the first film. The formula he was working on was supposed to alter or deactivate endomorphic genes, allowing one to naturally lose more weight, and in the first scene with Shelly the hamster it is implied to do just that. However, when Sherman takes the serum, over half of his body fat mysteriously vanishes in about 30 seconds, and his skin shrinks to fit.
* BaitAndSwitch: During Sherman's King Kong nightmare, he spots Carla in a hotel room, smashes through the window... and reaches past her for a turkey drumstick. [[ArentYouGoingToRavishMe The look on her face seems to show she's thoroughly insulted by this.]]
* BattleCry: After his first transformation in the remake. He proudly stands up on on top of the college he works in shouting this.
-->'''Buddy Love:''' I'm THIIIIIIIIIIIIIIIIIIIIIIIIN!!!!!!!!!!
* BluntYes:
--> '''Carla''': Professor, are you asking me out on a date? \\
'''Sherman''': *Bashful* Yes. Yes I am. \\
'''Carla''': I'd love to!
* BodyHorror: A completely tame example of this occurs whenever Buddy Love reverts back to Sherman Klump. Body parts become swollen as he regains all that excess body weight, and at one point he ends up with a grotesquely oversized lower lip.
* ButtMonkey: Dean Richmond whenever there's a hamster around.
* CatchPhrase: [[NoCelebritiesWereHarmed Lance Perkins]] has two: "Let's get busy!" and "Yes, I can!"
* ClusterFBomb: This film put television censors through their paces.
* DoggedNiceGuy: Sherman seems to have a history of being this.
* DysfunctionalFamily: The Klumps.
* FanDisservice: During his workout montage, Sherman is in desparate need of a powerful sports bra.
* FantasticDrug
* FatherlyScientist: Sherman, in regards to Shelley, an obese hamster he has great empathy and affection for.
* FightingFromTheInside: When Buddy attempts to take a life of his own, Sherman decides to fight back for control of his body. [[spoiler: In the climax, it becomes a literal case and he succeeds]].
* {{Gasshole}}: Cletus Klump.
** Sherman himself is a couple of times but only in dreams he has, when they are power oriented and are essential for his survival even in which his father encourages.
** Ernie Jr. is several times.
* GentleGiant: Sherman.
* GeorgeJetsonJobSecurity: Sherman gets fired once a film, and before then, the dean seems to always be looking for an excuse to get rid of him.
* GoldDigger: Dean Richmond is a shameless sycophant when it comes to any donor who shows interest in giving the school money for Sherman's research.
* TheHeckler: On his second encounter with the InsultComic, Buddy so thoroughly dismantles the guy it became a CurbStompBattle both comedically ''and'' physically.
* HeavyVoice: Played straight; the whole Klump family, Sherman Klump included, has a lower voice than Buddy Love, who inhabits the same body as Sherman but with less weight. In fact, of all the multiple characters he plays in both movies (being the Klumps besides Buddy Love), Buddy Love (even being the all time antagonist) is the only character Eddie Murphy plays using his real voice and appearance.
* HilariousOuttakes: About five minutes' worth during the credits.
* TheHyena: Buddy plays with it at times. It goes into full force when he encounters Reggie Warrington in person, ''especially'' during the "YourMom is fat" joke. Jason attributes it to high testosterone levels.
* IKnowYoureInThereSomewhereFight: Mama Klump tries to call for Sherman as he fights Buddy Love.
* ImagineSpot: Sherman has two of them, one where he buries Stella into the sand with his body weight, and one where he becomes so fat that he becomes a {{Kaiju}} terrorizing the city.
* InsultComic: Reggie Warrington.
* {{Jerkass}}: The insult comic Reggie Warrington.
** Buddy Love. He started out as a JerkWithAHeartOfGold before becoming an utter Jerkass.
** Also Granny Klump could be considered one because of how she not only talks the most cross of all the Klumps, but also because she is the least classy and is most crude and vulgar of them all. Even with the way she always insults Cletus and making them verbally always at each other's throats trading back and forth personal insults which always bothers Anna (Sherman's mother.) Not to mention how vulgar she is by going as far as the stunt she pulls on Buddy Love thinking that he is a male stripper which actually is bad enough to gross out a vulgarly perverted man like him to the point of making him vomit. These along with all the examples with her show you that she has the least moral conduct of all the Klumps.
* JerkWithAHeartOfGold: Cletus Klump, Sherman's father.
** Ernie Klump in some extent. He gives Sherman practical advice on him losing weight, by telling him to exercise. Sherman later takes his advice and actually succeeds in getting in shape during the TrainingMontage. [[spoiler: Of course Reggie had to ruin his self-confidence later on.]]
* MamaBear / PapaWolf: There is no doubt about it, that Cletus and Mama Klump love Sherman, so when his best friend and colleague accuses Buddy Love of murdering him this line cements it:
--> '''Buddy Love:''' ''(demonstrating his weight formula)'' I am about to make a 400 pound fat man disappear forever!
--> '''Jason:''' ''(arriving in time)'' [[BigNo NOOOOOOOO!]] [[BigDamnHeroes WAIT! I can not let you do this anymore!]] [[PunctuatedForEmphasis THIS- HAS GOT- TO STOP!]] ''(arrives onto the stage)'' Ladies and gentlemen... ''(points to Buddy)'' this man is trying to kill Professor Sherman Klump!
--> ''(audience gasps)''
--> '''Cletus''' [[PapaWolf That's it.]] [[TranquilFury I'm glad]] [[LetsGetDangerous I brought my knife.]]
--> '''Mama:''' [[MamaBear Mmm-hmm, and I got my razor.]]
* MeanBoss / DeanBitterman: Richmond, the dean of the university that Sherman Klump works at, frequently insults Sherman Klump's obesity and makes no secret of his contempt of Klump.
** JerkWithAHeartOfGold: Despite this, he did ally with Sherman Klump to stop Buddy Love from stealing the patent for the fountain of youth formula in the climax of The Klumps.
* MeaningfulEcho: Buddy to Dean Richmond: "Who you think you talkin' to, Sherman Klump? Man, if you ever talk to me like that again, I'll kill you. And I don't mean it as euphemism, I'm gonna literally kill you. I'm gonna ''strangle'' you and cut off ''your'' air supply until ''you'' pass away."
* MeaningfulName: The fact that the last name of the universally overweight Klumps sounds like "plump" is obvious. More so is that the slender love interest in the second Eddie Murphy film is named Denise Gains, especially when we're shown that Mrs. Klump's old wedding dress fits her.
* NightmareSequence: Sherman has a nightmare after he falls asleep while watchin TV, in which he grows into a rampaging giant and wrecks the city with a single fart that is ignited to cause an explosion.
* NoCelebritiesWereHarmed: Lance Perkins is a clear {{Expy}} of Richard Simmons.
* NoIndoorVoice: Buddy.
* NotHyperbole: Dean Richmond gives a memorable example.
-->''If anything goes wrong, for any reason... I'm going to kill you. And I don't mean that as a euphemism, I am going to literally kill you. I'm going to strangle you and choke off your air supply until you pass away.''
* NWordPrivileges: The Klumps and Buddy.
* OhCrap: Sherman when he wakes up next to three hookers after a night of partying (as Buddy), especially when Carla shows up.
* PainfulTransformation: Sherman is in terrible pain every time he transforms into Buddy Love.
* PayEvilUntoEvil: Buddy's putdown of Reggie Warrington.
-->'''Buddy:''' I've heard of dreadlocks, but shitlocks?
* PunchedAcrossTheRoom: Before the climactic fight, Buddy decks Jason towards the instrument set to prevent the magical vial from being confiscated, calling it a "short musical interlude".
* PunctuatedForEmphasis: The climactic scene where Sherman Klump and Buddy Love battle for control of the same body.
-->'''Buddy Love:''' "You can't beat me!"
--> ''(Sherman's side beats up Buddy)''
-->'''Sherman Klump:''' "YES! I! CAAAAAAAN!"
* ReadingsAreOffTheScale: Jason analyzes the data from the transformation and finds that Buddy's testosterone levels are dangerously high.
* SirSwearsALot: All of the Klumps, except for Sherman. Mostly, Cletus. Buddy Love definitely becomes one. The insult comic Reggie Warrington is definitely by far.
* SquirrelsInMyPants: Variation: During a demonstration test on the fountain of youth serum on a hamster, it initially works, but thanks to Buddy Love sabotaging the serum earlier, the hamster ends up basically turning Godzilla on them, forcing the audience to evacuate and the guards to fire on "hamsterzilla" before it dispatched them with turds. It then sees Dean Richmond (wearing a fur rug over himself in a failed attempt to hide) and, mistaking Richmond for a potential mate, gets very interested in him and is also strongly implied to have raped him. As the cameras were still rolling, this was also shown on TV across the state, if not the nation or the world, as the scene in the Klumps' living room revealed.
** It happened even earlier in the first film. Klump had accidentally let loose all the hamsters on the campus. one climbed into a student's pant legs. The girl he was talking to [[BiggerIsBetterInBed clearly mistook it as something else.]]
* StealthPun: The theater scene in the sequel. The original Nutty Professor was made a year after ''Film/CapeFear'', whilst in the remake's sequel, Buddy is laughing mad while watching the original in the style of [=DeNiro=]'s Max Cady's Iconic scene in the remake of ''Cape Fear''.
* StraightMan: Professor Sherman Klump. Debatably and most surely. Even though he's just as fat and kind of rugged looking as the rest of them, unlike how his enemy, Buddy Love looks, Sherman is the only one of all the Klumps who behaves most decent and most respectfully and is always good intentioned in all of his blunders. The only exception to his straightness might be when during the wedding dream scene that turns into a nightmare in the beginning of the second film, it appears that before the reverend says "I now pronounce you husband and wife", it appears that Sherman is staring at Carla's big breasts which have some cleavage in the wedding dress. It is followed by an erection scene following that which he is innocent from being because of being Buddy Love trying to come out of his trousers rather than being an erection caused by his lust for the assumingly noticed breast staring.
* ThatCameOutWrong: "Pardon me ladies and gentlemen, but I cannot go on living unless I have this man inside me right now!"
* ThatManIsDead
-->'''Buddy Love:''' SHERMAN IS GONE!
* TheTriple: Dean Richmond being a jerk to Sherman at the start of the movie.
--> '''Dean Richmond''': Can I get you anything? Juice? Coffee? Rack of lamb?
* ToiletHumor: The 1990s movie has a lot of fart jokes, as well as implied soiled pants. In both of them, the whole Klump family except for Sherman (including Buddy Love and some others) use foul language, and do socially revolting things.
** These scenes are actually parodying people who act exactly like this in real life. It's actually scary how accurately it portrays the Klumps.
* UglyHeroGoodLookingVillain: Sherman and Buddy.
* UncleTomFoolery: Sherman's family, especially his father Cletus. Buddy Love also indulges in it a bit.
* UndyingLoyalty: Jason to Professor Klump, he even goes as far as punching Buddy in the face when trying to stop him from eliminating Sherman for good.
* VillainProtagonist: Buddy at first, until it becomes clear that he's a completely separate persona and plans to take over Sherman's life.
* VirginInAWhiteDress: When Sherman brings Carla over for dinner, Grandma Klump notes that he can wear a white tuxedo, because "Sherman's never had relations."
* YourMom: Reggie cracks a "Your Mother Is Fat" joke to rile up Buddy[[note]] and the irony here is that he's indirectly referring to Sherman's mother, who really is fat. Buddy is actually Sherman's [[JekyllAndHyde literal alter ego]][[/note]] after [[LaserGuidedKarma he gets a taste of his own medicine from him]], but it only made Buddy feel unfazed and one-up him without any chance of allowing him a proper comeback. This results in Reggie breaking down and attempt to do a NoHoldsBarredBeatdown on him. However, he [[IKnowKarate fails at his "street karate"]] and Buddy [[CurbStompBattle Curb Stomps]] him.

* AbhorrentAdmirer: Grandma Klump to Buddy.
** Also, the hamster to Dean Richmond.

* ContinuityNod: Buddy mentions Carla from the first film.
* DarkerAndEdgier: The Klumps had a few moments of that range from dark humor to horror. Buddy Love in the second movie is more evil than he ever was in the first nor its predecessor. Going from trying to take Sherman's place to downright trying to stalk and destroy Sherman and anyone else that got in the way. Even before his DNA was separated from Sherman's, Buddy even found many ways to attack him on the inside, especially by hijacking his mind randomly. From giving him a terrible nightmare to saying and doing rude and embarrassing stuff at delicate times that alienates him from his father and love interest. That aside there were TearJerker moments too, from relationship problems between Sherman's parents mirroring Sherman's relationship with Denise, as well as breaking off the marriage under the belief that he can't be a good husband after his intellect is deteriorating from what he went and did to get rid of Buddy, especially due to an incident where Buddy Love sabotaged the fountain of youth formula and stole the actual sample, causing a test gone awry.

Luckily, it happens by a fountain, so when a tear from Denise drops on to his DNA structure and it lands in the water of it, Sherman is able to be revived by her and Clesius forcing him to drink it.]]
* OldShame: In-Universe, Buddy Love was this for Sherman, and he didn't tell Denise about him before.
* PowerWalk: The Klumps as they're headed to an all-you-can-eat buffet, where they eat every last piece of food in the place ''except'' the salad.
* RandomEventsPlot

* TookALevelInKindness: Dean Richmond by the end of the film.
