The Alibi: Towards the end, one of the bad guys is trying to elude the cops in a hotel, so in the corridor he grabs a woman coming out of her room in the corridor, stucks his gun in the small of her back and forces her back in the room to take her hostage. He locks the door, turns around... and discovers about fifteen cops pointing their guns at him. Turns out the woman's a detective, on a loosely related stakeout in the hotel. Whoops.
Bangkok Dangerous: In the original Thai version, two random street thugs make the mistake of targeting a deaf mute while on a date with a woman, not realizing he is a skilled hitman.
Big Trouble: The film's hitman makes a call from a pay phone. When gangstas approach him, he drops a napkin and, while bending down to pick it up, he produces a revolver from his ankle holster, points in their direction and says: Not right now. Okay?
Blade II: Vampires running a blood bank attempt to strap down a homeless man for a generous and involuntary donation, but the homeless man turns out to be a far greater monster than they are.
Blade: Trinity: A gang of vampires attack a woman pushing a baby carriage in a subway station. The "helpless" victim turns out to be Jessica Biel, resident Action Girl, and the baby turns out to be a booby-trapped doll. Unusually for this trope, she was deliberately trying to get attacked.
The Book of Eli: Done very frequently. It becomes much more hilarious/embarrassing when you realize that Eli might have been, in fact, a blind man all along.
In The Bourne Identity, Swiss police wake a man who is sleeping on a park bench. Instead of a bum, it's Jason Bourne, who takes down both cops in seconds. Bonus points for the fact that as an amnesiac he had no idea he was capable of doing that. This trope actually happens quite a few times in The Bourne Series as people either do not know what Bourne is capable of or underestimate his abilities.
Collateral: There's a scene where a couple of thugs steal a briefcase from a ziptied-up Max. Vincent confronts the two, one of whom brandishes a pistol right at him. A few double-taps to the chest and one in the head later, Vincent has his briefcase back.
The scene referenced in the page quote and picture.
The second film also has a random punk try to rob Dundee of his leather jacket.
Punk: What are ya chances of getting out of here with that jacket on? Dundee: (throws his knife, pinning the punk's mohawk to the wall) Better than average.
The second film has a similar sequence with a would-be hit man.
Dundee: You know, for a guy who supposedly makes a living killing people you ain't very good at it.
This became a "once per movie" trope, because the third movie also features a similar scene in which Dundee and his friend/rival Jacko easily disarm a group of robbers before trapping them in their own convertible by jumping on the roof.
Damien Omen II: A bully attempts to pick a fight with Damien Thorn. Not a good idea, as Damien is the Antichrist (although he didn't know it at the time).

Eddie then proceeds to take his wallet back, then takes the mugger's gun and cash.
Death Warrant: In the opening, a couple of gangbangers try to rob the hero cop Louis Burke (Jean-Claude Van Damme). He hasn't got time for them, being in the neighborhood solely to avenge his dead partner by catching his killer, so he quickly dispatches them and gets on with his mission.

Desert Heat: The Hogans unwittingly attack a warveteranEddie Lomax, who's on his way to deliver a parting gift of a motorcycle to an old friend (as his final act before taking a long journey), and steal said motorcycle. The only reason their inevitable demise is postponed is Eddie is too drunk to defend himself at the time of the attack.
Didier: In this French movie, some skinheads harass a mixed-race couple (nicknaming them "John and Yoko", as they look like the famous couple) driving a van. Only to find out the van is carrying a bunch of martial artists from the local "Tae Kwon Fu" [sic] club. Cue Neo-Nazis whomping.

Escape from New York: As Snake is wandering through the back of an old theater, tracking the President's homing beacon, he runs across an old man next to a fire. ("Hi Chief... Nice night. *looks down* Nice boots... Nice boots...") That's when the old man's henchmen step out of the shadows, only to find out the hard way why one should never mug a muscular guy wearing an eyepatch. The old man himself takes the hint when Snake puts him in the sights of his Uzi. (*flinches* "Easy now, chief... I'm walking... I'm walking...")
Falling Down: D-Fens is having sort of a bad day, and he doesn't take getting mugged by two gangsters too kindly. Revenge ensues and they get what they asked for a second time.

The Fifth Element: Some lunatic tries to rob Korben Dallas at his door. He is quite calmly convinced otherwise, and even hands over his gun. Which gets added to a pile of other weapons, presumably acquired in the same manner.
First Blood: The local small-town cops see Rambo as just a disreputable-looking drifter and start pushing him out of town. This turns out to be the last straw. (In the original novel, it's more a case of mutual misunderstanding than a real example of this trope.)
Ghost Rider: Johnny Blaze is arrested for the destruction he inadvertantly caused the first time he transformed into the Ghost Rider. Despite Johnny's insistence that he should kept far away from other people, the cops toss him into a large cell with about two dozen extremely rowdy criminals who immediately turn their attention on their newest cellmate. When it's all over, the only survivor is the one kid sitting in the corner minding his own business, who Ghost Rider claimed was an innocent, with his newly ruined jeans and a classic Oh Crap expression permanently frozen on his face.
The Godfather Part II: An elaborated one; Senator Geary tries to extort and bully Michael Corleone for a gambling license. A nonchalant Michael bides his time and turns the tables with a cold frame-up.

Hellboy: The backstory for Liz Sherman has her as a young girl running from a group of attacking kids who throw rocks as she tries to escape over a fence. It ends badly. She accidentally burns down the fence. And the kids. And the entire city block. Then again, since they were deriding her as a freak, they may have known about her powers and thus deserved to die.
Highlander III: The Sorcerer: A variation with a con scheme. Two street card hustlers try to rip off the immortal warrior Kane, but he uses his magic to turn the entire card deck into winning cards and takes their money. After he takes one guy's glasses with another magic trick when they protest, they take the smart option and run away.
A History of Violence: Two small-time criminals try to rob an Indiana town coffee shop with the intent to rob/murder/rape everyone inside it.

The misanthropic Officer Mooney performs an act of Police Brutality on a klown, thinking it's a prankster in a costume. The klown, which had been playing along with Mooney's attempt to arrest it, instantly bashes his head against the cell bars hard enough to kill him.
Happens a second time when a gang of bikers tries to bully another Klown. It decapitates one of them and chases the rest away.
Killshot: A fancy-talking hoodlum and wannabe Badass decides to steal the cadillac of a middle-aged man who looks dressed like a modern-day cowboy after the man grabbed a bite at a cheap diner. After driving around for a while at gunpoint they park the car somewhere, and the hoodlum peruses through his wallet. Then the man shoves a gun in his face and reveals that he's a contract killer. Interestingly he doesn't kill the punk, but hangs around with him for the remainder of the film.

The kids bullying young Clark.
The Mask: A comedic version occurs when a street gang makes the mistake of targeting protagonist Stanley just after he puts on the eponymous artifact for the first time. ("And last but not least, my favorite: a tommy gun!")
The Muppets Take Manhattan: A man steals Miss Piggy's purse. She screams after his retreating form, and then, very politely, walks up to a gentleman sitting on a bench and asks to borrow his roller skates. Hilarity ensues as the thief frantically tries to get away from Miss Piggy, who, of course, has her trademark psychotic look on her face. Later, when she gets him, and a cop takes him away, he makes a valiant effort at revisionist history:
Thief: She stole my purse! Miss Piggy:What?! Cop: Nice try, buddy.
Near Dark: As the film proves, trying to carjack a couple of vampires is a really bad idea.
Nothing To Lose: A car-jacking is how Terrance meets depressed Nick Beam. Boy did you pick the wrong guy on the wrong day.
Pirates of the Caribbean: Jack Sparrow flees to the blacksmith shop to get his shackles removed... only to find out that the blacksmith is Will Turner, who is not only the best swordsman in Port Royal but also the true love of the woman Jack just used as a human shield. It's only by "cheating" that Jack manages to escape intact.
Old Dracula: Dracula is accosted by muggers, but he doesn't even need to use his powers; he has a swordcane that is quite well up to the job.
Pee-wee's Big Adventure: Played with. While Pee-Wee is wandering the streets at night looking for his lost bicycle, he's attacked by a street gang. He snarls at them, hissing like a vampire. They run off in terror.
The Perfect Host: This is the premise. An attempted bank robber on the run fibs his way into the dinner party of a nebbish guy played by David Hyde Pierce, and threatens him with a knife once he's discovered only to pass out from some drugged wine the latter served earlier. Turns out not only is Pierce's character utterly Ax-Crazy, but he's also the police lieutenant investigating the robbery.
The Perfect Weapon: In this Jeff Speakman vehicle, a group of thugs attempt to mug Speakman's character, not realizing that: 1) he is a kenpo karate master; and 2) he had just been chasing down the man who killed his sensei and failed to catch him. What happens next is pretty much what you'd expect to happen to a bunch of thugs who catch a martial arts master in the worst of all possible moods.

Unusually, however, this example ends without bloodshed, Jules having tired of his life as a professional killer.

Predator 2: A gang of thugs attempt to rob a subway passenger, leading him to pull a gun on them. While this fails to disuade them, every passenger in the entire subway car proceeds to pull guns to back him up. Somewhat subverted, as it's the very escalation of violence that causes the Predator to stop simply tailing Harrigan's partners and go on a kill spree through the subway car.
RoboCop 3: A guy attempts to rob a doughnut shop. He gets lit up by twenty laser-sighted police firearms, from all the uniformed officers sitting in the shop at the time. The clerk turns to the robber and says "What's it like to be a rocket scientist?"

I've seen the headwaters of the Nile, and tribes of natives no white man had ever seen before. I've won and lost a dozen fortunes, KILLED MANY MEN and loved only one woman with a passion a FLEA like you could never begin to understand. That's who I am. NOW, GO HOME, BOY!
Sherlock Holmes: In the 2009 movie, two thugs try to rob Irene Adler. Bad move.

Superman: In the first Christopher Reeve movie, a mugger points a gun at Lois Lane and... Clark Kent. Since Lois was around, however, ol' Kal El couldn't open his special Kryptonian brand of whoop-ass on the crook for fear Lois would notice — although he did snatch the mugger's bullet out of midair when it otherwise would have hit her.
The Terminator: A trio of hoodlums decides that it's a good idea to pick on a Herculean naked man walking around at night. While it's generally not a good idea to start fights with crazed weightlifters, the punks probably would have been at an advantage had their intended victim not been a killbot from the future. Also played with, in that the Terminator is essentially mugging them (of their clothes, that is) before they decide to take out their knives.
Things to Do in Denver When You're Dead: The contract killer Mr. Shh (played by Steve Buscemi) stumbles upon a mugging in progress. When the muggers turn their attention to the weasely guy in the fedora, they end up on the receiving end of some Kung-Foley.

In the Wayne and Shuster, "Dr. Jekyll and Mrs' Hyde", Jekyll is on the comical rampage as the clownish villain Mrs. Hyde and is about to be attacked by Jack the Ripper. Hyde easily beats him up and robs him, followed by a headline, "Jack the Ripper Ripped Off!"
Vampires Suck: Almost happens when the trio menaces a fisherman. He knows Tae-Bo and punches one of them in the face repeatedly. Unfortunately for the fisherman, the vampires kill him anyway.
Wolf: A classic example occurs in this film, starring Jack Nicholson. Jack's character, Will Randall, is taking a nighttime stroll through Central Park (as a Werewolf), a trio of hooligans attempt to mug him. Needless to say, Will found a finger in his pocket the following day.
Mugger: Hey buddy, can we borrow some cash? Will: All of ya? Well I've got about a thousand dollars on me, how much would you like to borrow? Five? Ten? (carnage ensues)

Eli: It's not our way! Book: But it's my way.
Subverted in X-Men: First Class. When young Erik goes on a crushing spree in Shaw's office after the murder of his mother, his random attacks never reach Shaw, since he has neither the control to aim them nor the immediate metal on Shaw's person to offset that weakness. Even if he had the chance, though, Shaw's powers would have easily stopped Erik from harming him.
Young Frankenstein: Seen in a deleted scene, where a highwayman calling himself "Jack Spratt" (he tells this straight to the camera; there's a reason it's a deleted scene) tries to mug young Frankenstein's monster. Bad move.
