The Avengers in "Who's Who???" (subtitle: "Steed goes out of his mind. Emma is beside herself."). Steed and Emma's minds are switched with those of two enemy agents. They did not switch voices, if only because the plot demanded that the enemy use the heroes' hijacked bodies to infiltrate British security. In an amusing touch, after each commercial break, the episode also includes a "reminder" about the swap to the viewer, but the supposedly helpful voice-announcer merely gets progressively more confused.
2009 ITV comedy-drama Boy Meets Girl, where Martin Freeman's DIY store worker and Rachael Stirling's fashion journalist are swapped.
The Buffy the Vampire Slayer episode "Who Are You?", a typical example of the similarity between Freaky Friday Flip and Not Himself, due to characters in one another's bodies acting in atypical, often outrageous ways. It includes a scene in which Faith, now in Buffy's body, takes a long bath and explores her new anatomy. And then a scene in which Faith enacts a most unusual version Rage Against the Reflection, pummeling and shouting at her own body.
In the Angel episode "Carpe Noctem", an old man swaps bodies with gym hunks, with the side effect that the strong bodies eventually melt under the strain. But when he takes over Angel, he realizes he has a body that will last. Angel is stuck plodding around a nursing home, being restrained by orderlies, until his friends figure out what's happening and fix things.
Appears in the Dollhouse episode "Belle Chose." Echo is imprinted with a bubblehead college student a professor wants to seduce, while Victor has the mind of a comatose serial killer uploaded into him (to make an interrogation possible). Then their minds get swapped, and... it becomes hilarious and scary all at once.
In the Charmed episode "Enter the Demon", a spell causes Paige and Phoebe to switch bodies. Also another story "Lost Picture Show" has Leo and Piper constantly arguing about their marital life which causes them to see a soothsayer who swap their bodies.
8 Simple Rules: Cate watches the film, then next morning awakes to find she and daughter Bridget have swapped bodies. However, son Rory has swapped with his hamster, and Jim and CJ have also swapped — leaving Kerry, still in her own body, feeling very left out.
Phil of the Future did this in two episodes: once in "Neanderphil," when he switches with Curtis, and again in "Versa Day," where he switches with Pim.
In the Farscape episode titled "Out of Their Minds," everyone on the ship switched bodies twice. This episode was somewhat atypical in that they actually mentioned (and showed) the characters taking the totally logical step of getting acquainted with their new equipment. Oh momma! This episode is also notable for their solution to the problem of remembering who is in what body — printing name tags with their real faces and wearing them around their necks. After the second body-switch happens, there's a few moments of them trading nametags.
Especially notable for the acting. The actors, even the puppeteers and voice actors, nailed each other's vocal inflections and body movements impressively, all the more impressive considering that some characters (notably, Pilot and Rygel) aren't shaped at all like the other characters played by human actors.
In the appropriately named Lizzie McGuire episode, "Those Freaky McGuires", Lizzie and Matt swap bodies after an argument. Disney as a whole absolutely loves this bit.
The Outer Limits episode "The Human Factor". At a US nuclear base in Greenland, a psychiatrist uses Applied Phlebotinum to mind link with an unstable military man. Just then, an earthquake hits, somehow causing the two men's minds to enter each others' bodies.
In the Out of Jimmy's Head episode "Out of Jimmy's Body," a magic pelvis outfitted with Japanese technology causes Jimmy to switch bodies with Sonny, enabling Sonny to see the cartoons in Jimmy's brain (since the brain itself remains in Jimmy's body). At the same time, Robin's body is switched with her elderly piano teacher's, and Dad's body is switched with the piano teacher's parrot.
Used in a Mighty Morphin' Power Rangers episode. Curiously, after the Blue and Pink Rangers switch bodies, the normally glasses-bound Blue Ranger, logic not withstanding, still needs them in his new body. Much like the Kim Possible example below, the ramifications of being stuck in a body of the opposite gender were barely touched. Nor was the fact that both characters should have been adjusting to temporarily having different powers.
Power Rangers Samurai has continued it with Switchbeast, who inflicts this on people via his Combat Tentacles. Unusually, he switches people with objects (specifically, objects likely to be thrown in compactors or recycling smelters) instead of with each other. However, this is used against him by Mike and Emily. Emily grabs his second tentacle after he's shot the first into Mike, and jabs it into him. Then Mike (in Switchbeast's body) temporarily switches him into a soccer ball to rough him up and force him to attack his body's weak spot (with Mike's body) and switch everyone back.
The Prisoner did this once, with an episode for which Patrick McGoohan was not available. So Number 6's mind was put into someone else's body (and tasked with finding the inventor of the mind-swap machine, or else he'd never get back to his own body...). Strictly speaking, this lacked most of the standard bits of the "swap" aspect, as Number 6's body was portrayed as lying sedated for the entire episode.
Quantum Leap was just one huge Freaky Friday Flip combined with Body Surf in premise. Although it rarely played that way, since the actor playing the main character was always on screen rather than the character with which he was switched.
In the Red Dwarf episode "Body Swap", the voices also swap with Chris Barrie doing a Liverpool accent during the scenes where he's playing Lister. Leads to a Grand Theft Me when Rimmer refuses to leave Lister and later hijacks the Cat's body.
Played with a twist in Space Cases as the characters don't switch bodies, only races, after each character complains someone else on the ship has it easier. The swaps also swap most of the character's hair styles as well, for no understandable reason. In addition it proves that the really happy and really pessimistic ones are that way by genetics.
The episode "Holiday" has Daniel Jackson and a dying old man named Machello swap bodies in a Grand Theft Me, while Jack O'Neill and Teal'c exchange bodies by accident in a more traditional Freaky Friday Flip. Unlike most versions of this trope, the actors totally nailed the impression of the other character. Teal'c-in-O'Neill and O'Neill-in-Teal'c are so obviously who they're supposed to be that it works beautifully, and is utterly hysterical.
General Hammond: How did it go, Colonel?
Teal'c (in O'Neill): It did not go well, General Hammond.
O'Neill (in Teal'c): Ya think?
The Ancients devised a communicator that operates on this trope. It's shown up in a few episodes throughout all three series, and is the Destiny team's only link to Earth in Stargate Universe.
As shown in one episode of SGU, killing a person using the stones results in both dying (i.e. the person whose body it is and the person whose mind currently occupies it).
An episode of Engine Sentai Go-onger has the Red Ranger Sousuke switch bodies with the Monster of the Week, leading to a particularly odd scene where Sousuke's soul is shot from the team's combined weapon to get him back in his proper body.
Some episodes later, the team's Combining MechaNon Human Sidekicks (who need to have their Soul placed in a diecast version of themselves — it's a merchandising thing), end up in the wrong bodies entirely when Hant, Go-on Green, takes control of the Monster of the Week battle.
In the earlier series of Dekaranger there was an episode where Hoji's mind is swapped with that of an alien criminal and must somehow tell the team they've been swapped. The plot was later carried over into an episode of Power Rangers S.P.D.
An episode of Kaizoku Sentai Gokaiger involved a Zangyack general using his powers to swap Don and Luka's bodies. Luka uses this as an excuse to try out boy's clothing, save some girls, and act cool, while Don has to run away from some men that want Luka to work for them as a jeweler. The villains also plan to use this; having Sgormins swap bodies with the leaders of the world and ally their countries—and eventually, the world—with the Zangyack Empire.
In the miniseries The 10th Kingdom, the evil queen makes her pet dog switch places with the country's prince, who starts to go "doggy" after being in that form for too long.
On 3rd Rock from the Sun, the Big Giant Head swaps Dick and Sally for one episode. Even though the behaviour changes among the two visitors, many other characters remain oblivious to the change (including Harry). However, Don was able to detect Sally's mind by intuition, but was pulled back into Reality when he turned.
In Lost Girl, an escaped mental patient named Reynard injects gorgon blood into the beer. At first Reynard possesses Bo's body, and Bo is sent into Limbo. Later, Bo jumps from Limbo and causes everyone to swap. Bo swaps with the bounty hunter named Boraro, Hale swaps with Ciara, Dyson swaps with Kenzi, Reynard enters Lauren's body, and Lauren is sent into Limbo.
In "Ten Little Warlords"/"Intimate Stranger", Xena and Callisto switched bodies (due to a Real Life Writes the Plot incident, with Lucy Lawless breaking her pelvis in an equestrian stunt).
Xena also shared bodies with at least two other characters over the course of the series: Autolycus, in a spirit possession (also cross-referenced with Not Quite Dead and Almost Kiss), and a young noble girl in the requisite "fairy-tale"/Aesop episode.
The X-Files two-parter "Dreamland", where Mulder swaps with the sort of shadowy agent he's usually trying to find, played by Michael McKean. In this case the actors also switched places. The viewer sees Mulder, everybody else sees the other guy, including the mirror.
Arguably the darkest example in television, the Fear Itself episode "Family Man" features a loving, church-going husband and father who swaps bodies with a sadistic serial killer after a car accident. Jailed for the other man's crimes (which include torturing, raping, and killing at least 26 people), he watches helplessly as a monster takes over his life and family. Our protagonist finally escapes from jail and manages to return to his own body... only to learn that the killer has butchered his wife and son, leaving only his young daughter (who was presumably raped) alive — and fingering him for the crime.It's a finish so depressing that it rivals anything on the Outer Limitsrevival.
Gilligan's Island, "The Friendly Physician". A mad scientist swaps the minds of our castaways into different bodies. Strange for live-action is that the voices of the inhabitants stick with the transfer and are dubbed in.
The Legendof William Tell in The Tomb of the Unknown Warrior. Will and Drogo switch briefly - Drogo-in-Will takes it far worse than Will-in-Drogo, running off in a panic. Two guests are also switched, and one promptly dies, leaving the other stuck in the wrong body.
Main plot of the Argentine telecomedy Lalola (and the several foreign remakes of it, mostly called Lola). A man switches bodies with a woman and has to adapt to the female life. S/he only actually meets the other person at the very ending of the series, so s/he is under the impression that s/he simply switched gender. Gradually, she becomes more and more female in mind and falls in love with a man. In the end, she is offered the chance to switch back, but she chooses to keep living her new life.
Kamen Rider Kiva pulled a variation on this when a visit to a psychic somehow causes the spirit of Wataru's late father Otoya to possess him. While in the present, Otoya helps Megumi resolve a crisis, learns of the joys of the Internet and maid cafes, helps complete a violin Wataru was working on, and provides subtle Foreshadowing.
Supernatural, "Swap Meat", in which a geeky seventeen-year old with a flair for dark magic swaps bodies with Sam so he can enjoy the perks of being a "stunning-looking man" and get close enough to Dean to kill him.
Played with on The Young Ones, in a scene where the lads' actors are switched, trading costumes and personas. No reason is given for why each of the four characters looks different — it's that kind of show — and none of them actually notices the change, aside from Neil's remark that he's not feeling himself.
Robert Louis Stevenson's bookends cause this, in the Warehouse 13 episode "Merge With Caution". First to a thief and a security guard, then Myka and Pete. Then the pairs merge into one that keeps switching. Then the first pair explode. Thankfully, Myka and Pete prevent this last.
Main plot of episode number six of the Japanese drama Anna-san no Omame (a.k.a. The Best Friend of Beautiful Anna).
In the Wizards of Waverly Place episode "Quinceañera", Alex switches bodies with her mom to avoid her titular 15th birthday party. Which is okay with Theresa, who never got a Quinceañera and always wanted one.
Twice: In the episode mentioned above, and the episode titled "Family Games Night", where Alex switches with Harper, and the body switching spell ends up going wrong in the end.
Subverted in Pair Of Kings where this was planned for Boomer and Brady with 2 of the strongest guards but instead Lanny and Mikayla end up sharing a body with Boomer and Brady instead.
Happens to Aethelwynne and Sgt. Riley as the result of an accident involving a plasma ball and the transporter in the Pixelface episode "Body Swap".
In the same episode Dean Pelton amusingly tries to do this with Jeff, but Jeff refuses to play along.
A Eureka episode revolves around Carter randomly swapping bodies with other people who were in the Matrix. First it was with Fargo in the middle of Fargo's "evaluation" involving laser tag... causing Fargo-in-Carter to pull out Carter's gun and start shooting before he realized what was going on (no one was hurt). Meanwhile, Carter-in-Fargo aced Fargo's "evaluation" by calmly tagging Warren Hughes in the chest multiple times thanks to his US Marshall training. He then nearly failed the psychological test (i.e. looking at Rorschach-like pictures and saying the first thing that comes to mind), since he was answering like a normal person and not a PhD/nerd. They flipped back just in time for Fargo to answer correctly. Carter and Zane then swapped right as Carter and Allison were about to "celebrate" him getting back into his body, while Zane was taking a shower with Jo. The final swap was between Carter and Allison... as she's inserting a brain probe into him. Allison-in-Carter has to guide Carter-in-Allison on extracting the probe. All actors do a pretty good job at imitating one another.
