* ''WesternAnimation/YoungJustice''. Red Volcano shrugs off being dropped from a great height and blasted with Blue Bettle's plasma cannon.

* Happens in ''Film/BladeII'' when Blade says, before setting off the light grenade,
-->"You obviously...do not know...who..''you're''...''FUCKING WITH!''"

'''Raiden:''' [[ScrewThisImOuttaHere I know enough to go to Tahiti.]]\\

* ''ComicBook/WonderWoman1987'': Circe murmurs ''"You've got no idea what you're getting into."'' with a little smirk when Medusa has Circe teleport her outside the embassy so that she can kill Athena's [[Franchise/WonderWoman current champion]].

* A Website/{{Twitter}} user once tried to correct a joke Creator/GailSimone had made about ComicBook/ThePunisher's personality. When he didn't make the connection even after having it pointed out to him that she was a comic book writer, Gail replied, "Dude, between the two of us, which one has actually written the Punisher, do you think?"

* ''Film/MenInBlack''

* ''[[Fanfic/TheHeartTrilogy Heart of Ashes]]'': When [[{{Seers}} Kathryn]] decides to stop being submissive in front of [[PlotIrrelevantVillain Lord Beronor]] when he tries to intimidate her into obedience, she uses this line. His response is to [[WouldHitAGirl backhand her]] and [[TranquilFury calmly]] make his exit while throwing the line back at her.
-->'''Kathryn:''' You are little more than a dog scrounging for food at the King's chair! I am more than what you or that weakling of a king could ever dream of! You have no idea who you're dealing with-- ARGH!\\
'''Lord Beronor:''' And apparently... neither do you.

* ''WesternAnimation/JackieChanAdventures'' - "The Masks of the Shadowkhan"
-->'''[[ArcVillain Tarakudo]]''': You have no idea who you are dealing with.\\
'''[[OldMaster Uncle]]''': Enlighten me.\\
'''Tarakudo''': [[KneelBeforeZod Bow before Tarakudo]], [[BadassBoast King of all Shadowkhan]], [[MyNameIsInigoMontoya Lord of all Oni]]!\\
'''Uncle''': ''*gasps*'' So you ''are'' [[OutsideContextProblem Japanese]]!\\
'''Tarakudo''': ''*knocks Uncle down with a [[MindOverMatter telekinetic]] strike*'' [[DeadpanSnarker Consider yourself enlightened.]]

* In the film version of TheMusical ''Film/LittleShopOfHorrors'', Audrey II sings in "Mean Green Mother From Outer Space":

** In ''Literature/DarthPlagueis'', it becomes apparent by the end that Plagueis really has no idea what he's dealing with when it comes to his incredibly cunning, incredibly vicious apprentice, [[TheSociopath Sidious]].

It can often also be said by those who intend to [[ScrewThisIndexIHaveTropes Screw The Rules]] because they have [[ScrewTheRulesIHaveConnections Connections]], [[ScrewTheRulesIHaveMoney Money]], [[ScrewTheRulesIHaveSupernaturalPowers Superpowers]], or because [[ScrewTheRulesIMakeThem They Make Them]].

Another variant is someone saying this phrase ''for'' the other as a warning that you're dealing with someone that could be dangerous, serving as an indrect BadassBoast in the person's steed.

** Post-time skip had the fake Straw Hat crew attempting to hunt down a girl who refused to drink with them and the boy who attacked them with a plant [[spoiler: Who happened to be the real Nami and Usopp]]. The Fake Luffy later "captured" someone who had earlier humiliated him [[spoiler: who was none other than the real Luffy himself]]. Interestingly, none of the real Straw Hats openly broadcasted the fact that they were the authentic ones and when the Fake Straw Hats found out that they had interacted with the real ones, their reactions were appropriately stunned and terrified.

Kellerman, Dana. Twenty-nine. Took shrapnel in the shoulder during the Gulf War. Still takes pain-killers for it.\\

-->'''Kathryn:''' You are little more than a dog scrounging for food at the King's chair! I am more then what you or that weakling of a king could ever dream of! You have no idea who you're dealing with-- ARGH!\\

--> A university class is writing an exam. At the end of the exam period all of the students pass in their exams and leave, except one. He stays there for two more hours finishing his exam before going up to the professor to hand it in.\\

* In ''Literature/PrinceRoger'': The titular prince gets to use the phrase verbatim at a petty gangster. The gangster doesn't know who the prince is, and assumes he's a petty criminal setting up a restaurant as a front for petty crime with a group ex-military and scary-looking aliens for muscle. He's right until the word "front". The team is instigating a counter-coup, the ex-military are very much current military, and the scary-looking aliens don't just ''look'' scary.

'''Spike:''' No, you got off easy too. ''(stands)'' Do you know how much blood you can drink from a girl before she'll die? I do. You see, the trick is to drink just enough to know how to damage them just enough so that they'll still cry when you ...[snip] You wanna know what I've done to girls Dawn's age? ''(beat)'' This is me Buffy. You've got to kill me before I get out.

* Played straight most of the time in ''Series/{{Lucifer}}'' as people don't really believe that Lucifer Morningstar is the Devil, despite him being quite open about it. However it is played for laughs in one scene where Lucifer is being evicted from his nightclub. He advances on the moving crew in fury and gives this trope, but instead of a terrifying display of supernatural power, the next scene shows that Lucifer has [[APartyAlsoKnownAsAnOrgy brought out the girls and booze]] and [[BoringButPractical got them all drunk]].

** Rowan tries to instil fear in a possible opponent by asking them "Do you know who I am?" Rowan isn't actually anyone of note, but he does excel at bullshitting his way out of his problems.

--->'''Hawking:''' ''You've got no idea what you're messing with here boy.''

* ''VideoGame/TeamFortress2'' - The Scout in "Meet the Scout".

* Ronnie Pickering is famous for this trope, using the very similar meaning phrase "Do you know who I am?" when trying to intimidate someone in a road rage argument.

-->'''Viggo:''' It is not ''what'' you did, son, that angers me so. It's who you did it to.\\

** Later it turns out that, [[SelfDemonstrating/TheJoker the man]] he was talking to, ''the mob'' had no idea [[NotSoHarmlessVillain how dangerous]] ''he'' was.

* Said in the ''Creator/NicholasSparks'' movie ''The Lucky One'', by the boorish ex-husband of the female half of the featured couple to the male half. The man counters his threats by informing him that he ''does'' know what kind of a person he's dealing with, having spent years in the military.

* Subverted in [[http://explosm.net/comics/3843/ this]] ''Webcomic/CyanideAndHappiness'' strip, in which a diner repeatedly asks a waiter, "Do you know who I am?". It seems like he's using it to get his own way, but the punchline is that [[spoiler:he's suffering from amnesia]].

* PlayedForLaughs in ''Series/TheDickVanDykeShow'' episode "[[ Recap/TheDickVanDykeShowS1E14BuddyCanYouSpareAJob Buddy, Can you Spare a Job?]]" as Buddy's replacement Jackie Brewster heckles Mel.

** Another serious case in "Never Leave Me". Spike's [[RestrainingBolt chip]] and soul seem to be failing, and he begs Buffy to kill him, citing she has no clue what he can ''really'' do

''Spike:''' I'm not talking about the cellar. The people in the cellar got off easy. I'm talking about me. Buffy, you have never met the real me.\\
'''Buffy:''' ''(crosses arms)'' Believe me, I'm well aware of what you're capable of.

-->'''Man''': Some of these guys are meant to be pretty good. Delta Force, I think.
-->'''Micro''': I don't care if they're God's own anti-son of a bitch special forces. He'll go through them like a buzzsaw.

-->'''Kathryn''': You are little more than a dog scrounging for food at the King's chair! I am more then what you or that weakling of a king could ever dream of! You have no idea who you're dealing with - ARGH!\\
'''Lord Beronor''': And apparently... neither do you.

-->'''Lieutenant''': I think we can handle one little girl. I sent two units, they're bringing her down now.
-->'''Agent Smith''': No, Lieutenant, your men are already dead.

-->Ya don't know what you're messin' with.
-->You got no idea.
-->Ya don't know what you're lookin' at
-->When you're lookin' here.
-->Ya don't know what you're up against,
-->No, no way, no how.
-->You don't know what you're messin' with,
-->But I'm gonna tell you now!

-->'''Moss''': If I was cuttin' deals, why wouldn't I go deal with this guy Chigurh?
-->'''Wells''': No no no. You don't understand. [[ImplacableMan You can't make a deal with him.]]

-->'''Macleod:''' Don't do it Bill...I can't afford to lose another man.
-->'''Mook:''' You got a lot of faith in me, don't you Macleod.
-->'''Macleod:''' Faith can move mountains Bill, but it can't beat a faster draw. There's only three men I know with his kind of speed. One's dead, the second's me. And the Third Man is Cole Thorton.
-->'''John Wayne:''' There's a fourth.
-->'''Macleod:''' Which one are you?
-->'''John Wayne;''' I'm Thorton (cue the mook with an OhCrap face.)
-->'''Macleod:''' See Bill? Aren't you glad I didn't let you draw?

-->'''[[CorruptCorporateExecutive Jonathan]]:''' Do you have ''any'' idea who you're dealing with?!
-->'''[[BigBad Nicolae]]''': [''[[PsychoticSmirk smiles]]''] [[TheAntichrist Do you?]]

-->'''Cop:''' DO YOU KNOW WHO THE FUCK I AM?
-->'''Robber:''' ''(yanks off his badge and nametag)'' We do now, jerkoff.

-->'''[=McClane=]''': Ellis, Ellis, you don't know who you're dealing with. They're going to kill you! Tell them you don't know me!
-->'''Ellis''': Oh, John, how can you talk that way after we've known each other for years!

-->'''Viggo''': It is not ''what'' you did, son, that angers me so. It's who you did it to.\\
'''Iosef''': Who? The fucking nobody?\\
'''Viggo''': That fucking nobody... is John Wick.

--> '''Merchant''': Don't you know who I am?!
--> '''Learchus''': [[BrutalHonesty No. Nor do I care]].

-->'''Bill Buchanan''': You have no idea what you're dealing with, you little ass kisser!

-->'''Cordelia:''' You don't know who he is. Oh, boy... you're about to get your ass kicked.

-->'''Mr. Ashet:''' You have no idea who I am, do you, Miss Raiden? Or of the [[PortentOfDoom dire importance of recent events]].\\

-->"You don't know who you're dealing with, do you, boy? I mean, really. I ''crap'' better magic than this."

-->'''Josh''': [[DramaticIrony You guys don't realize it]], but [[PreemptiveDeclaration you're having a really bad night.]]

--> '''Shepard''': I sacrificed hundreds of human lives to save the Destiny Ascension. I unleashed the Rachni on the galaxy. So for your sake, I hope your escape plan doesn't hinge on me hesitating to shoot a damn hostage.

--> '''Melvin''': You really have no clue what your fucking with here, do you?\\
'''Joey''': Uh, yeah, I'll just be getting out of the way now.
--> '''Melvin''': Yeah that's what I thought.

--> '''Melvin''': The man did not know what he was fucking with.

-->'''Director Tagg''': All of this goes someplace. Do you really see yourself making it five more years without being killed or put in prison?
-->'''Skitter''': I haven’t really thought about it.
-->'''Director Tagg''': I have. Bad publicity fades with time. So do welts and scabs. Five or ten years from now, provided the world makes it that long, nobody will remember anything except the fact that we fought back. Good publicity will overwrite the bad, carefully chosen words and some favors called in with people in the media will help whitewash any of our mistakes. We’re an ''institution.''
-->'''Skitter''': So you think you automatically win? Or you’re guaranteed to win in the long run?
-->'''Director Tagg''': No. They didn’t pick me to head this city’s PRT division because I’m a winner, ''[[spoiler:Ms. Taylor]]''. They picked me because I’m a scrapper. I’m a survivor. I’m the type that’s content to get the shit kicked out of me, so long as I give the other guy a bloody nose. I’m a stubborn motherfucker, I won’t be intimidated, and I won’t give up. The last few Directors in Brockton Bay met a bad end, but I’m here to stay.
-->'''Skitter''': You hope.
-->'''Director Tagg''': I know. You want to fight this system? I’ll make sure it fights back.

-->'''Sodarn Insain''': Do you know who I am?!\\
'''Yakko''': Why, did you forget?

--->'''Grim''': [[YouFool Foolish mortal!]] [[TranquilFury I don't think you know who I am...]] Let me give you a hint! ([[SummonToHand conjures up]] [[SinisterScythe his scythe]] and chops off the head of the mop before looming closer with a BladeReflection, leaving Gladys [[OhCrap suitably terrified.]])

-->'''Jasper''': [[SmugSuper I've seen what you really are.]]\\
'''Garnet''': *chuckles* [[PreAsskickingOneLiner No, you haven't.]]
