An episode has Wayne getting a newspaper to the groin after the paperboy chucked it. Wayne comments that the paperboy has been working out.
A later episode has him get another one during training from a kung-fu master that claims that Wayne is the chosen one to stop the ninjas from conquering Matheson. Wayne comments that he is hemorrhaging from the attack and hopes that his training would finish or that there would be no 3rd Szalinski child.
An old sketch had a man volunteer to be the big-helmeted "attacker" in a women's self defense course, and ended up spending an evening getting his groin repeatedly stomped on by the participants.
A sketch with Will Ferrell and guest star Katie Holmes involves the two as actors doing a scene where she squeezes (and then kicks) him in the groin over and over again with each take, at the dismay of Ferrell.
Nerf Crotchbats. As the rap jingle of this commercial parody attests, the Crotchbat is "A hard steel core, covered with Nerf/You'll feel the difference when you hit the turf!" They offer the Nerf Crotch Missile, too!
In the pilot of Nick Swardson's Pretend Time, a child is dying, and one of his dying wishes on his Bucket List was for a stranger to stick his penis in a fishbowl full of piranhas.
Given all the grief House puts his patients through, it's surprising that so far, only one disgruntled relative has kneed him in the groin. That was a particularly painful looking instance, though.
Meanwhile, in another episode, a patient's testicle exploded. It also just happened to explode in the face of the resident pretty boy whom House just so happens to love to torture. This is not so surprising once you realize that the entire episode was All Just a Dream on House's part.
A newly-freed Thirteen delivers one to a man as a favor to an ex-cell mate.
Played straight with lethal consequences: While Chiana struggles for a gun with a male character, the gun goes off. After the initial confusion of which character was shot, the male character falls down, and the camera pans to reveal a smoking gun hole in the crotch area. The reveal of the exact location of the wound was one of the many scenes that was edited out of Farscape when aired in different countries.
As Moya's crew turn against one another in "Crackers Don't Matter", Chiana knees Crichton in the groin. The fact that Crichton started hallucinating after this is thankfully coincidental.
Subverted in "Hot to Katratzi". Upon meeting the Scarran who had ordered Aeryn and her cut open in the previous episode, Chiana asks if Scarrans have "mivonks" and kicks him hard in the groin. She then falls over in pain clutching her leg.
The episode "Two Balls, Two Strikes" has a bizarre plot centered around this. Earl tries to make up for kicking this angry Jerkass in the groin (his idea of fun involved cutting off Randy's hair, putting it in water and forcing Joy to drink it) and finds out that the jerkass has become mellow since his balls are deformed and he is getting less testosterone.
Also in the episode "Stole a Motorcycle", Randy remembers back to a point where Earl was chasing him down a highway wearing the bottom half of a giant chicken costume. Once Earl catches him, they wrestle for a bit, before Earl kicks Randy twice in the groin. This is made more hilarious by the fact that he kicks him with giant chicken legs.
Enjoyed on the Fox show Titus. Titus warns his friend about Erin's very sassy teenage niece. When it happens to the guy, he has the classic reaction. the second time, however, when she kicks Titus, she immediately falls to the floor clutching her knee, while Titus knocks on his well protected crotch. "Rookie."

In the first movie, Chris Pontius hooks up a car battery electric muscle stimulator to his scrotum.
Vincent Margera (more often known as Don Vito), the obese uncle of skateboarder Bam Margera, is the target of a variety of blows to the gonads in Viva La Bam. This has happened a few other times, usually from Bam.
Subverted/Averted in an episode of Reaper after The Devil allows Sam to attack him with a baseball bat; although he doesn't feel pain, he thanks Sam for being classy enough not to go for the balls.
In the Mystery Science Theater 3000 episode Space Mutiny, the main character not only hits a man in the crotch, but then shoots him there as well. While played serious in the original film, Mike Nelson is quick to riff this: Mike: (as the victim) Ow, why do you hate my groin so much?
Sheldon's twin sister says that if Sheldon doesn't stop trying to dictate who she sleeps with, they'll have to 'go round like when they were little', to which Sheldon lurches away reflexively, shielding his crotch. Eventually, he says the wrong thing. Gilligan Cut to him lurching out of his room, holding his crotch and talking in a strained voice.

Kensi: So what? It would've been better if I'd pistol-whipped him across the face?
Deeks, Callen and Sam: Yes!
Highlander had a flashback where Duncan was training with a female Immortal, May-Ling Shen. When Duncan made a remark about her, she kicked him in the crotch and told him, "Man's greatest asset is also his greatest liability."
Even Doctor Who had one, in the classic series no less. Near the end of "Mark of The Rani", The Rani gives The Master a very unpleasant kick (cue newsgroup discussion on whether this means Time Lords have bollocks or if it doesn't count since The Master was in a hijacked body...).
In the last episode, "Only The Good", Rimmer kicks Death in the balls and runs away. "Remember, only the good die young!"
Rimmer seems to be a favourite character to be involved in these attacks. He gets groin attacked in Back to Earth and Cassandra, and gives himself a voluntary groin attack (it makes sense in context) in Back in the Red.
Legion threatens to do this to himself if the crew continues misbehaving, since any pain he feels will be felt by the crew. Kryten is understandably unperturbed.
Kryten: That kind of tough talk doesn't scare us! Others: Yes it does!
In the series 5 episode "Demons and Angels". While Lister is being remote controlled by the lows due to an implant in his spine, he attacks his crewmates. He strangles Cat for several seconds while Rimmer orders Kryten to blow his kneecaps off. Because Kryten is paralysed with indecision, the Cat decides there is only one way to stop Lister. With a hearty, meaty THWACK, Lister's eyes bulge, his mouth goes slack, and he releases the Cat.
In the final episode of Blackadder II, Blackadder and Melchett escape from German captors by carefully memorizing their daily routine, then striking at the moment where they're at their weakest — when they taunt the prisoners with pelvic thrusts. Afterwards Blackadder remarks, "Trust me to get the hard one!"
In the "Viral Hour" episode, during the "Fainting Goat" segment, Tory gets clocked in the groin by a playful goat. (Okay, he probably didn't think it was funny, but at least one viewer did.)
He got one earlier than that when they were testing the Ben Franklin kite flying myth. Their kite was having stability problems, so they tied a rock to its tail. Tory was standing next to the kite when it suddenly whipped around and smacked him in the groin with the rock. We then get a shot of Grant sitting on the ground, laughing hysterically. Bonus points for this being seconds after Tory dubbed it the "death kite" and the "kite of punishment" after it took a swing at his upper body.
During the "Plywood Builder" revisit, Tory donned padding before the test ... and Grant decided to test it with a knee to the crotch.
During the Mythbusters top 25 countdown, after talking about the above mentioned incidents, Tory wonders if he still can have kids.
Averted during the Mythbuster Challenge between Adam and Jamie. To test pain endurance, they had a duel with pain(t)ball markers, one shot each per round, stepping closer each round, until one cried uncle. Jamie managed to shoot Adam in the belly button twice (with Adam noting that it hurt worse the second time). One of Adam's shots (unintentionally) hit Jamie in the groin, which did nothing because they were both wearing cups. Unsurprisingly, Adam lost.
In the How I Met Your Mother episode "The Goat" Ted punches Barney in the groin after being offered "one free shot" as punishment for Barney breaking the Bro Code by sleeping with Robin, Ted's ex-serious-girlfriend.
Also in season six, Barney and Ted do this to each other to try and make Marshall laugh after his father's death.
The Pre-nup has Lily think up the idea of a electric collar to keep Barney in line. Or a shock ring.
"Wait a minute, I'm confused, if it's not around my neck then where is the shock collar...oh...god..."
Marshall's brother punches him in the groin after asking him if he likes crushed nuts and then again if Marshall needs help with grabbing his bags.
In Drop the Dead Donkey, the Globelink team go on a bonding paintball weekend. At one point, Henry storms into view ranting about Joy being a psychopath, and then the shot widens to reveal his crotch is covered in yellow paint.
Jeremy Clarkson did this to James May during a challenge involving the presenters trying to escape a roadblock in home-converted stretch limousines. With a paintball gun. At point-blank range.
May: That was chuffing agony.
And Richard Hammond headbutted poor May in the groin during the Vietnam challenge, when he (and his motorbike) fell over onto him. Both of them seemed to think it was more funny than painful.
When they were coming up with car-related art, Jeremy puts paintballs into the airbox of a Formula 1 car so they would be shot out of the exhaust and onto a canvas. The canvas wasn't strong enough to withstand the high-velocity paintballs, and Jeremy was stupidly standing right behind it. You could actually hear his screams through his helmet, over the sound of the F1's engine. After donning a cup, he used a sheet of aluminum as a canvas.
While showcasing a flaw on Jeremy's Porsche 944 he was using for a challenge, Richard and James slam both doors which immediately causes the sunroof to fall in. On the swing back after shutting it, May inadvertently pops Clarkson.
The Chinese Attack Stig came out of nowhere at the end of the Chinese Cars segment to deliver one to James.
Clarkson: In the plums!
Barely averted in Odyssey 5. Hedonistic scientist Kurt Mendel has an attack of paranoia and is convinced that his friends are Synthetics (artificial humans). His former lover, Angela Perry, gets Kurt to swallow his medicine by pointing a Beretta 9mm at his testicles.
Angela: I will do it, Kurt! Kurt: Oh God, even as a Synthetic, you are a ballbuster...
In "Oil", Vyvyan swings a cricket bat square into Rik's crotch while he's prone on the ground, leading to Rik's immortal line:
"Ha, ha, joke's on you, missed both my legs."
Rik slips and falls down the stairs, hitting every wooden support in the banister groin-first. By the time he reaches bottom, he has a pile of broken-off banister pieces between his legs and an expression more bug-eyed than anguished.
While not a groin attack, it's worth mentioning that it subverts the idea of women never being hit in the chest for comedic purposes. The gang is having a game of American football in one episode. Monica throws the ball to Phoebe who catches it, but it strikes her in the chest hard. However, it is played for laughs as she squeals: "Oh! Broken boobs!". Since she flashed Chandler not long after, we can assume nothing permanent was done.
Also, The Stinger in the episode "The One With Rachel's Going Away Party" where Rachel is moving to Paris and the gang helps to pack her stuff away, Joey asks Phoebe to kick him in the spuds after he's stuffed a load of styrofoam down there. Unfortunately, not enough.
Choujin Sentai Jetman subverts this. Gai Yuuki would target mooks' groins, but instead of striking it, he'd squeeze them to unnerve the Mook, before beating them in the more proper place.
But played straight with Kaori and Ako as Raita usually ends up on the wrong end of their knees and kicks. Kaori also did this to her Jerkass fiancé in Episode 4 as he told her to forget her friends and that Kaori refused, kicking him in the family jewels while wearing her wedding dress.
This segment on Attack of the Show! covered a montage of female examples created in the battle simulation game Fight Maker 2. This led to backlash from various feminist blogs such as Feministing, who blamed the creators of Fight Maker 2, believing that they had created some sort of misogynist vagina-punching game.
In one episode, a French film takes place in a trash dump. In one scene a nun kicks a policeman in the groin.

In a retrospective episode of Murphy Brown, Murphy is having labor pains in the hospital, and a male coworker is annoying her with "Tell me what you're feeling! I want to know the pain that only a woman can feel!". She beckons him to come close. Cut to him sitting on a stool, months later, describing the events to the audience: "Well, I didn't get to feel the pain that only a woman can feel, but I did get to feel the pain that only a man can feel."
Happens in the Goodies episode "Hype Pressure". Context: Bill has become a sixties-era flowerchild, and refuses to sing a violent song on Tim's show. This ensues:
Bill: Sorry, man, you're not getting that. From now on, I am a child of peace. Tim: I'll smash your face in. Bill:(hands over a flower) Love. Tim:(drops it and grinds it into the floor with his shoe) Bill: ...(looks around, then grabs Tim by the shoulders and knees him in the groin — as Tim's doubled over in pain, Bill starts flashing the peace sign everywhere) Love, love, love.

The heretic priest who got his groin split in two on his own invention during the Spanish Inquisition as punishment for building the device in the first place, though this is more Karmic Death...he DID build the device, but he was accused of being a heretic and thus was the first victim... Hoist by His Own Petard.
To add on to this list, the Portuguese man treating Brazilians like slaves and forcing them to pan for gold. While swimming in the Amazon River, he stops to urinate, and gets a candiru fish to lodge into his urethra. As if that wasn't disturbing enough, he rips the still lodged candiru out (and therefore, the inside of his penis), spilling out blood which attracts a school of piranha that eat him alive.
"Hertz So Good": A man with a "Prince Albert" penis piercing dies from being shocked by an old electrical transformer. The episode has a shot of him lying on the ground, smoke curling around his crotch.
The bitter gymnast who dismounted off a trampoline — and lands on top of one of the supports for the parallel bars. The force was enough to rip her rectum and vaginal opening and cause fatal damage. Doubles as Impaled with Extreme Prejudice.
The abusive football coach who died of sepsis after the star kicker of his team kicks him in the crotch — with cleats that have lead insets in them (the force of which sent a bone fragment into his kidneys). Usually, when men get kicked in the groin, they wish they were dead. In this case, there was no wishing.
The very first episode of Brazilian series As Brasileiras has the protagonist getting jealous at her husband and using a kitchen knife on his Teeny Weenie. Then she discovers her jealousy was without reason, and Hilarity Ensues in order to reattach his manhood...

Before the thug is able to cause any trouble to them, Imogen immediately kicks him in the groin from within a surprising state and as he falls down in pain, Imogen asks Terry "I think that hurts, yes?".
She Spies plays this trope from time to time, with the three female spies usually striking their opponents where it hurts the most.
The Comedy Central/Atom.com online series Hot Sluts also plays this trope as well, with the girls of the nightclub (most notably Irena) kicking or kneeing perverted men from within sight.
In the Lois and Clark episode, "Battleground Earth", Lois knees a corrupt U.S. Army Colonel in the family jewels after he tells her that he plans to use a deadly type of kryptonite gas against Superman.
Another episode has her doing this to the Prankster when he tries to suffocate her with a pillow, causing him to double over in agony.
Balls of Steel's Pain Men, really two-thirds of Dirty Sanchez, spend one episode playing a game of conkers using their testicles as targets.
This Indonesian troper still remembers one from Indonesian 1999 Superheroine TV Series, named Saras 008, which is, as the creator admitted, partly inspired from Cat Woman and Sailor Moon. In one episode, the main character's ally, a man who is also a superhero (I forgot the superhero's name, but I'm sure the actor's name is Pino Bahari), fight against two midget mooks who completely realize that could be Curb-Stomp Battle for them. So what do they do? One of the mook keep the superhero busy, while the other sneak behind him and kick him in the nuts! Then, since it's only enough to made the superhero let his guard down but not really enough to incapacitate him, those two mooks tasered him.... fortunately not in the groin again, but in his leg, which is still enough to render him unconscious.
What makes this more irony (or funny?) is, perhaps, that the superhero is actually a boxer in his normal life, but he doesn't seem to have a Balls of Steel since he can't stand the pain he received and caused himself to let his guard down, thus allowing the two midget mooks to be able to took him down. Additionally, he obviously wasn't wearing protective cup undearneath his costume.
This one is also from Indonesia, from other superhero 1999-2001 TV series, named Panji Manusia Millenium (Indonesian word for "Panji The Millenium Man"). There's at least one episode where a comic relief character (a friend of Manusia Millenium himself) dreamed to be like Manusia Millenium. One night while he was sleeping, he had a nightmare where Manusia Millenium is killed by Donclo (The Big Bad who is also a Super Villain). In this nightmare, before drawing his last breath, Manusia Millenium entrusted the said comic relief character his power to continue his legacy. Afterwards, the comic relief awoke from his sleep. Although he realized it was just a dream, he somehow convinced himself that it's real and he's actually able to be a superhero. So one day, he went out to help a woman (whom he had crush and she's actually Panji's love interest, too, no less) from a bad guy by impersonating as Manusia Millenium himself! At one point, during the fight, the impersonator is attacked in the nuts. He might be just an impersonator, but it's not everyday to see a superhero, even if he's not real, is received an attack in his groin, right?
Oh, there's actually another in the aforementioned Nightmare Sequence, although this might be Played for Drama. Do you want to know how exactly Donclo in the dream killed Panji? He cast an energy ball and aimed it at Manusia Millenium's groin! What made this funny, however, that Panji didn't immediately suffer the attack's effect, thus made him to look at his groin to find out what the hell is that energy ball doing in his groin, before the effect is unleashed several seconds, causing him to suffer an understandably excruciating pain! And this is done twice, no less! The first attack only managed to wound him. At the second attack, Donclo cast a much stronger energy ball and aimed it again at Panji's poor balls. And just like before, the attack's effect isn't immediately unleashed and fatally wounded Panji before several seconds elapsed. And just like before, Panji done nothing to evade or stop it except look at his groin to find out what the hell is that energy ball doing in his groin during aforementioned several seconds. Afterwards, once again, the excruciating pain is obviously seen suffered by Panji who painfully scream and shows painful expression. Then, it's pretty obvious there are smoke pop out (created with poorly CGI effect, which undestandable considering its year of production) from Panji's groin, before he collapsed and succumbed to death with his fatal wound in the nuts.
The Japanese dorama Otasuke Girl featured a schoolgirl character called Moroi Ayumi who used, in self defence and to chastise irritating boys, her signature attack, the "Gold Crush". This was simply a firm kick in the groin, was featured a bare minimum of once per episode, and was later adopted by Otasuke Girl herself.
Robber: Do you know how painful this is?
Otasuke Girl: I don't know, because I'm a girl!
In Haven, the villain William is in Synchronization with Audrey. In "The Lighthouse", he boasts that this means nobody can hurt him without harming her as well. Nathan says he thought of a loophole and kicks him in the nads. It works.
Played for Drama
Oz features Johnny Post getting dismembered, his penis cut off and mailed to the Homeboys, as a retaliation for burning Dino Ortolani alive.
Beecher memorably bit off the tip of Robson's penis when Robson tried to make him perform oral sex. Whether or not this belongs in the section above depends on the viewer.
Agent Scully of the X-Files firmly believes in groin attacks when defending herself. In fact, it's pretty much the first move she makes. Justified in that she's a medical doctor who knows the best ways to hurt people, she's a small woman who knows better than to try to grapple with male attackers, and she's an FBI agent who's trained to be a combat pragmatist.
Vala Mal Doran does this to Daniel Jackson in a fight in Stargate SG-1. Rather than a kick however, she hits him with a fire extinguisher. Can be seen as funny, considering the whole scene is that Daniel is getting beat up by a girl, but his reaction is more realistic.
In the KateModern episode "Back on Brick Lane", Gavin, who is having a mental breakdown, chases after and pounces on Jennifer - a complete stranger - mistaking her for Kate. Jennifer knees him in the groin and runs off, yelling hysterically. Gavin lies on the ground, coughing and sobbing.
Taken to an extreme in Blackadder. The title character is punished by being strapped into a torture chair which will simultaneously cut his hands and feet off as well as attack his balls with a drill.
There is also this: "the booted bony thing with 5 toes will soon connect sharply with the soft dangly collection of objects in your trousers."
On The Wire, Snoop and Chris try to torture Omar's friend Butchie to find out where he is. When he refuses to crack, they finish him off by shooting him in the groin.
Probably a rare example of this occurring on a female is Don Draper's attack on Bobbie Darrett in Mad Men.
In Spartacus: Blood and Sand, a very well endowed gladiator recruit gets crucified and castrated, much to the dismay of his sponsor, who bought him because of said asset. She should have thought twice before she told him to go kill Spartacus, whose life was considered far more valuable than that of a gladiator trainee.
On ER, two hoops-playing doctors half-jokingly discussed which body part(s) they'd be more willing to lose, given a Sadistic Choice between amputations. The most difficult choice? Whether to lose two arms or one penis.
Deadliest Warrior has an inadvertent Groin Attack by the Aztec representative using the Atlatl & Tlacochtli. One of the show's host claims one could survive an arrow to the groin; he is alone in that belief, if the wincing the others did is any indication.
Up to Eleven, in the Celt vs Immortal episode, where a Celt was shown slicing a man's groin in a battle with his sword.
Methos from Highlander pulled a notable example once, when Stephen Keene, a genuine good immortal who believed Duncan was evil came after Duncan. When Methos couldn't talk Duncan into being sensible about the whole issue, he promptly incapacitated Duncan, then fought Keene in his place. At one point during the fight Methos fakes a fall, which makes Keene move in for the kill. Methos blocks the attack, then brings out a concealed dagger and stabs Keene with it below the belt. An outraged and horrified Keene barely manages to croak out "You bastard" before collapsing.
On an episode of Law & Order: Criminal Intent, a Yandere seduced the current wife of her ex-brother-in-law online by pretending to be a British man and then gave her cocaine laced with dioxin. She instructed the other woman to vaginally insert the drugs, which killed her. That's right: she pulled off a groin attack by tricking a female into killing herself with chemical laced coke. She later justified herself by saying the wife was not a good girl because she would shove drugs up her crotch.
There is also a Law & Order: Special Victims Unit episode where a serial rapist married one of his rape victims (she didn't know he was her rapist). At the end during The Reveal, the woman says "You're the man who raped me!?" and instantly pulls a Groin Attack on the man (using her knee). Cue a quite priceless look from Stabler as they duck his head while he groans in pain to stuff him in the police cruiser.
Subverted on another Law & Order SVU episode, when the police doctor is collecting samples from a suspected pedophile, who whines that it hurts when she plucks hairs from his head. Stabler and the doctor point out they'll need pubic hair samples too, clearly anticipating his distress at getting painfully plucked there as well; the suspect, however, drops is trousers to reveal that he'd already had his groin rendered permanently hairless by electrolysis.
In the same episode, one of the pedophile's victims burned and mutilated the crotches of his little sister's dolls to act out his anger.
A rare female example happens off-screen in one episode. A woman kicks her younger brother's who was actually her son therapist right between her legs when she mistakes the therapist's rather controversial methods for signs that the therapist was seducing him. The team gets involved because the injuries look like evidence of rape and the guy becomes their prime suspect though he ultimately turns out to be the only pure victim in the whole mess.
The classic USA Network series Silk Stalkings had used this trope from within a straight daily basis, in which a woman would usually either kick or knee a man in the groin. This video is pretty much a compilation of some of the groin attacks seen from within the show.
Tales from the Crypt. In "Split Personality", after being caught by the twins he was conning, Joe Pesci's character is tied into a bed and is forced to see much to his horror as the twins cut him in half using a chainsaw. And guess where they started cutting him? Right in his groin. Ugh.
At the start of the episode "And All Through the House", the greedy wife who had killed her husband earlier finds herself being attacked outside the home by a hideously-deformed man who's dressed up as Santa Claus and upon managing to cut a part of his face with an icicle, the greedy wife kicks him in the groin, stunning him long enough for her to make an immediate break for her home.
Near the end of Friday The 13th: The Series episode "Better Off Dead", Ryan and Jack are able to rescue Micki from the villain of the episode, but Micki, who was experimented on earlier by the villain who had the episode's cursed object in his possession, savagely attacks her friends from within a feral-like state and during the scuffle, Micki strikes Jack in the groin with a back mule kick, knocking him down to the ground and leaving him in a state of extreme pain for a few minutes.
Another episode of the series, titled "Crippled Inside", had a young teenage girl named Rachel Horn being attacked by four teenage boys during a "supposed date" with one of them. When the leader of the group has Rachel pinned to the ground so that he can attempt to have his way with her (in other words, Attempted Rape), Rachel knees him in the groin so that she can immediately get up from the ground and attempt to escape from him and his friends.
Angelus:(mocking) You can't do it. You can't kill me. (she winds up... there's the kick...) *WHACK* Buffy: Give me time.
The season 5 finale also has a rare female example. It's hard to see due to the pace of the fight, but at one point Glory clearly punches Buffy in the groin. And yes, it hurts just as much for women, and Glory is a god... ouch.
Also, repeated with emphasis and a very sharp axe in the series finale.
Caleb: Stupid girl. You'll never stop me. You don't have the— Scythe:*THWACK* Buffy: Who does nowadays?
This was off screen, otherwise it'd be permanently affixed as the trope image.
An episode of Nash Bridges has the female lead, Caitlin Cross (played by Yasmine Bleeth) being attacked by a Russian mobster at a nightclub while she's undercover as a prostitute.

Not only that, but Sofia (said Mama Bear) then leaves him to bleed to death..
Heroes: Although the actual action is shown just out of the shot, it's clearly obvious from Sylar screaming in pain that Peter shot him in the groin with a nail gun after successfully blocking Sylar's powers, beating the living daylights out of him, and then pinning him to a table with said nail gun.
Gentarou Kisaragi, Kamen Rider Fourze, gets nailed in the groin by the Chain Array Module early on.
Game of Thrones gives us Brienne shoving her sword up between the legs of a rapist. Later on, "The Boy" castrates Theon Greyjoy, and the camera cuts away before the actual Groin Attack. In Season 4 when Brienne battles Sandor Clegane, bothCombat Pragmatists use this technique in short order, with Brienne's injury shown to be just as agonizing as Sandor's.
Done in LazyTown when the "evil dude" either attacks Sportacus Bill or the other way around. At one point his "biggest rival" Hulk Hogan does this to him.
In Continuum, Kiera shoots Travis in the groin. His protective suit saves him from being castrated, but the impact still hurts enough to incapacitate him.
