Harry Dunne is a 30 year-old former dog breeder, and part time self-employed dog groomer from Providence, Rhode Island. He is best friends and roommates with Lloyd Christmas. He is the secondary protagonist of the 1994 film, Dumb and Dumber as well as the 2003 film, Dumb and Dumberer: When Harry met Lloyd and the 2014 film, Dumb and Dumber To along with Lloyd Christmas.


Harry was born to a loving single mother and like Lloyd, an Absolute idiot born. The exact fate of his father was never truly explained. Because of his idiocy and poor grasp of reality (As he truly believe his imaginary pirate friend Captain Ron was real well into his teens) Harry's mother knew it would be impossible for him to fit in socially with other children and home schooled him until he was a teenager. His mother decided to take a chance and allow Harry to attend regular High school where Harry would meet his life long friend and fellow idiot, Lloyd Christmas. In 1994, Harry accompanied his roommate and best friend Lloyd Christmas to Aspen to deliver a suitcase to Mary Swanson.

In the beginning, Harry learns that one of Lloyd's limousine passengers, Mary Swanson, left a mysterious briefcase behind unaware that she was turning in ransom money to get back her kidnapped husband Bobby. Harry is seen being fired from his pet grooming job. He mourns the murder of his pet parrot Petey, but thinks that Petey's "head fell off" from old age. Lloyd thinks that life is not cooperating with them and convinces him to leave their clueless lives to Mary's hometown: Aspen, Colorado, meet up with Mary and return the briefcase to her.

They get stuck in several obstacles on the way to Aspen, Colorado. They are targeted by a mean thugish 6' 4" trucker named Sea Bass who blames an accident on Harry and soils his burger. In revenge, Harry and Lloyd trick Sea Bass into paying their bill added in with theirs and along with other purchased items added in; and although escaping, Sea Bass vows revenge. Then Lloyd needs to pee really bad and Harry suggests to use beer bottles in their van to urinate in. Lloyd then relieves himself in about 5 bottles. While Lloyd takes care of it, they get pulled over by a snobbish police officer who accuses them to DUI. The officer then grabs a bottle and tries to drink what he believes is beer. Harry and Lloyd try to dissuade him but he tells them to shut up before drinking the urine. Upon drinking it he groans and growls an order to "get the hell out of here!" and as they drive off the officer vomits on the road.

Then they pick up a man named Joe Mental as a hitchhiker. They are unaware that Joe is one of Bobby Swanson's kidnappers who wants the briefcase to give to the primary kidnapper: Joe's life-long friend Nicholas Andre. Mental is frequently annoyed by their stupidity and is forced to suffer annoyances of stuff like their tag wars ending with one of them arguing over whether or not "you can triple stamp a double stamp"; the most annoying sound in the world; and an annoying version of popular song "Mockingbird"'.'

At a restaurant, to drain his annoyance against Harry & Lloyd, he dares them to eat hot atomic peppers at the same time. In retaliation, Harry and Lloyd put peppers in his cheeseburger as he makes a phone call unaware that Mental has ulcer problems, and thus cannot eat acidic atomic peppers. Joe Mental decides to kill them with rat poison, but changes his mind when he learns that they have no idea on what is in the briefcase. When Mental has a reaction from the peppers, he falls backwards on the ground groaning from the agonizing pain in his stomach from his ulcer problem, he orders them to get his medicine, but they end up accidentally giving him the rat poison. Mental then blames Harry for it with his final words calling him an "SOB" and then dies of the toxins and Harry and Lloyd flee guilty of killing Mental. 

That night, Harry and Lloyd learn that they are now wanted by the police as fugitives for Mental's accidental death. As they stop at a gas station, Harry falls in love with a woman that is also moving to Aspen, Colorado to get away from her boyfriend. Harry tries to ask her on a date, but sets himself on fire by accident. As he burns, he gets impatient with her getting off topic of her phone number, screaming "For God s​akes just gimme the damn number!!" Offended, the woman drives off refusing the offer and Harry charges into the bathroom to put out his burning leg and sees Sea Bass lying on the ground KO-ed and Lloyd sucking his thumb in fear (Sea Bass found Lloyd and tried to sexually molest him and murder him in revenge).

That night, Harry promises not to mention another word of Lloyd being in the bathroom with a trucker with his pants down. After the next stop at a gas station, Lloyd ends up accidentally driving the wrong way running them out of gas. This proves to be luck because if they reached the Colorado border they would have been arrested for killing Mental due to officers tracking them down. The next day, Harry wakes up in Lincoln, Nebraska in fuel milage drama. Nearly out of gas, they stop on a pullover site. Infuriated with Lloyd for his dimwittedness, Harry decides to walk back to Providence, Rhode Island. However, Lloyd realizes that the truck is not completely out of gas and drives to a nearby town trading it for a moped. He then catches up with Harry who grows happy with Lloyd for his idea and accompanies him on the moped all the way to Aspen, Colorado. After arriving in Aspen, they are unable to find Mary due to her last name being forgotten.

That night, while camping in a blizzard Harry even with a campfire cannot warm his fingers. When Lloyd reveals extra gloves on him, Harry gets enraged that his own friend did not give him extra gloves when it was clear that Harry was freezing. In return for it, Harry tackles Lloyd trying to strangle him, dropping the briefcase opening it to reveal the money.

They decide to use the money to buy a fancy hotel room in Aspen, a new car, among other posh items and track down their spendings with IOUs. They end up spending every penny of the ransom money and eventually find Mary. Lloyd gets shy and asks Harry to ask Mary on a date for him. Harry agrees but ends up asking Mary for a date for him and her. Harry lies to Lloyd that Mary will come for Lloyd the next day, but he really sneaks out of the hotel to attend his date with Mary. On his date, Harry shows his stupidity by licking a frozen flagpole getting his tongue stuck to it; putting a snowman's face in the wrong part of the snowman; among others but Mary thinks it is intentional humor. Eventually, Lloyd learns that Harry arranged it for himself.

Angered with his friend for his treachery, Lloyd pretends to be normal as Harry prepares for another secret date with Mary. While Harry is sprucing himself up, Lloyd pours laxatives in Harry's coffee and forces Harry to drink it in a so called toast for their friendship. The laxatives act up while Harry is about to go with Mary on the date. The drink forces Harry to use the Swanson mansion toilet and when he finishes, he finds that the toilet cannot flush. Stuck now with fixing the entire mess, Lloyd uses advantage of this pickle to pick up Mary and take her to the hotel to get her briefcase. Eventually, Harry figures out that Lloyd did it out of vengeance and decides to go to the hotel to reconcile, but is picked up by the woman he shouted at in the Gas Station for an unmentioned reason.

When he arrives he spots Lloyd and Mary handcuffed to the room bed. He finds himself being captured alongside his two buddies by Bobby's kidnapper Nicholas Andre who is enraged with Harry & Lloyd for spending the ransom money. While Nicholas Andre tries to book an escape to Europe, Harry and Lloyd angrily rant over who is in fault for ruining their friendship causing Andre to order them to both shut up and decide who is shot first. Harry ultimately decides to take the bullets, but survives and retaliates against Nicholas with 5 missed shots from a pistol he somehow got. Then FBI agents rush into the room ambushing Nicholas and arresting him. The woman turns out to be an FBI agent who is the leader of the kidnapping case; she used Harry to capture Nicholas and provided Harry the gun and bulletproof vest; but she shows some antagonism towards Harry when she says that the FBI did not care if he was fatally shot or not but about capturing Nicholas off of it.

Eventually, Bobby is found and safely reunited with Mary. Harry and Lloyd Do NOT get a heroes reward being that they put the cops and feds through so much trouble and aggravation. Now with their trip useless and their bought possessions confiscated to pay their IOU debts, Harry and Lloyd decide to journey back to Providence, Rhode Island, unknowingly turning down an offer to become oil boys for girls going on a national bikini tour. They redirect them where a town may be for them to find oil boys. They are then seen continuing the journey back home, playing games of tags and quitsies.


Harry was an incredibly unintelligent man, although he showed signs that he was slightly more intelligent than Lloyd on some things. He was also suprisingly charismatic, as Mary Swanson took quite a shine to him. He was prone to unintentional accidents which usually brought disaster on himself and/or anyone in the vicinity.
