You Have No Idea Who You're Dealing With

Go To

Liam Hennessy: You have no idea who you’re dealing with.
Quan: Yes, I do. Do you?

A common Stock Phrase often spoken to a character who, well… you know. Can be played for laughs or as a threat (especially when the "who/what" in question is really a Not-So-Harmless Villain). Someone who can easily mop the floor with the fool who's trying to pick a fight, but doesn't feel like doing so at the moment, might say this as a final warning to back off.

Can also work with three characters, usually The Villain, The Hero, and someone else who's picking a fight with the villain, not knowing who they're dealing with — while the hero does, having faced them before, and tries to warn the third character before they get themselves killed.

It can often also be said by those who intend to Screw the Rules because they have Connections, Money, Superpowers, or because They Make Them. Very commonly heard by a person suffering (or believing themselves to be suffering) from Recognition Failure at a place that only allows the famous and the wealthy entry when they realize they are Not on the List.

Occasionally inverted as a bluff, when actually they're nobody the challenger would be impressed with anyway. Still, it's Truth in Television.

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 indirect Badass Boast in the person's steed.

  • One Piece:
    • 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 who happened to be the real Nami and Usopp. The Fake Luffy later "captured" someone who had earlier humiliated him 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.
    • Also the Straw Hats (minus Robin) when they first met Aokiji didn't fully understand how powerful the Marine's top people could be and how far Luffy and the others had to go before they even remotely stood a chance against one third of the Greatest Military Powers. Not long after that, the Straw Hats meet Kizaru, and then Luffy meets Akainu; those three remain the only ones who have ever made the Straw Hats seriously angry – while actually being their enemies – and gotten away with it.

    Mook: You got a lot of faith in me, don't you Macleod.

  • Men in Black does it with a dramatic zoom on Kay after he dismisses the "illegal aliens" in order to interrogate the ALIEN, and he's had enough of the protests from Border Patrol.

  • Mr And Mrs Smith: John and Jane Smith say this to each other after they tumble to the fact that they're assassins for rival organizations.
  • Although he doesn't say the trope exactly, in No Country for Old Men Carson Wells tries to get the gist across to anyone who asks him about Anton Chigurh. He has mixed success.

    Wells: No no no. You don't understand. You can't make a deal with him.
  • In Pitch Black, Riddick uses this twice.
    • First when Fry tries to convince him to come back to save the other survivors, and he suggests she abandon them and come with him instead.
      Fry: You're fucking with me, I know you are.
      Riddick: You know I am? You don't know anything about me. I WILL leave you here.
    • And a second time, retroactively, after killing a vicious alien in hand-to-hand combat:

    You obviously know exactly who you're messing with... but... why?
  • A sex slave broker in Taken tries to use this line verbatim on Bryan. Bearing in mind that Bryan has already torn through half the broker's associates to find him and is currently in the process of shooting out the creep's arms and legs to cripple him, it's safe to say Bryan knows exactly who he's dealing with, and he does not care — if anything, the slaver doesn't know who he's dealing with, if the speech about his "particular set of skills" is any indication. The sequel reveals the sex broker's threat wasn't empty as his family comes gunning for Bryan, but Bryan is just that bad-ass and ends up tearing through them as well.
  • The Usual Suspects. The protagonists are doing an armed robbery of New York's Finest Taxi Service.
    Robber: (yanks off his badge and nametag) We do now, jerkoff.

    Professor: You can't hand in your exam two hours late! You get a zero!
    Student: What?! This is an outrage! Do you have any idea who I am?!

    Student: Good.
    The student then sticks his exam in the middle of the stack and leaves the room.

  • Artemis Fowl - "Stay back, human. You don't know what you're dealing with."
    • Gets even funnier in the Time Paradox when Artemis says to his younger self: "Stay back, you don't know what you're dealing with." It didn't work that time either.

  • The Bronze Horseman by Paullina Simons. A Communist Party official makes the mistake of saying this to Captain Belov, only to end up against the wall with a rifle across his neck while Belov points out that he doesn't know who he is dealing with.
  • Discworld:
    • In Thief of Time, Lu-Tze has this done for him by the dojo master, who offers to provide "the name of the man you are about to destroy," but is dismissed by the martial arts student facing Lu-Tze down, who doesn't think he needs to know a sweeper's name. The dojo master chastises the student and states that the question wasn't directed at him, whereupon Lu-Tze introduces himself and the student fills his pants.
    • The History Monks demonstrate their awareness of this trope in their first rule of martial arts: "Do not act incautiously when confronting little bald wrinkly smiling men."
    • In Snuff, Sam Vimes apparently gave a speech about this, stating that the only facet of a suspect's identity a copper should care about is the fact that they are a suspect. He gets his words thrown back into his face after attempting to invoke this trope on the rookie cop who's trying to arrest him.
    • Averted when Susan rides her grandfather's horse to find a witch. The witch immediately recognizes Death's horse (whose name is Binky) and says, "Ooh, miss, if you've stolen that horse, you've got no idea the trouble you're in."
  • In the first novel, after Erast Fandorin is captured by a baddie for the nth time, said bad guy proceeds to explain that the conspiracy Fandorin is targeting is much bigger than he thinks.
  • In Peter David's Knight Life, when Gwen (Queen Quinevere reincarnated) summons a demon, it tells her that she has no idea what she's screwing with. She says just enough to prove she knows exactly what she's screwing with and then binds it to her will.
  • The Lord of the Rings: if you are familiar enough with the series cosmology, this is basically what Gandalf's famous "You cannot pass!" speech to the Balrog amounts to. He is announcing himself as a Maiar, a being of equal stature to the Balrog itself; making it clear he knows exactly who and what the Balrog is; and telling it to go away or risk its death at his hands. The Balrog does not listen, and ultimately pays the price.
  • Mindstar Rising by Peter F. Hamilton. Greg Mandel breaks into the residence of a Knowledge Broker who coordinated a hacker attack on Event Horizon, who responds this way. Greg just grins and points out that's exactly why they've turned up—to find out who The Man Behind the Man is. Shortly after someone fires an Energy Weapon through the window to make sure the broker doesn't reveal this information.
  • In Prince Roger: 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 of 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.
  • Professor Moriarty says that to Sherlock Holmes in The Final Problem referring to himself and his organization.
  • Star Wars:
    • Used and subverted in one of the X-Wing novels. Two mooks are scared off from hassling Corran Horn and Mirax Terrik when they find out that Mirax is the daughter of notorious smuggler "Booster" Terrik. One of the mooks had initially tried this line on Mirax, who retorted that she doesn't care who he is, and then the bartender warns them about who her father is. Later, Corran tries the same thing on someone bidding against them for some parts and weapons, only to find that the other bidder is "Booster" Terrik.
    • In Darth Plagueis, Darnada, the son of a local crime boss, says this to Magister Hego Damask. Hego says it right back and, given he is one of the galaxy's wealthiest beings and sponsors their criminal organization, a more senior member slaps Darnada for the insolence and forces him to apologize to perform damage control. And unbeknownst to both of them, Hego is the civilian identity of Darth Plagueis himself, meaning Darnada really didn't know who he was dealing with.
  • We get this marvelous subversion from Graham McNeill's Ultramarines series. An important merchant tried to invoke this on Sergeant Learchus, whom he had just witnessed picking up a supply truck by himself and placing it back on the road, then forbidding the convoy from leaving the city.
    Merchant: Don't you know who I am?!
    Learchus: No. Nor do I care.

  • Breaking Bad: The morning after Walt drunkenly implies he had some connection to Gale's death, Skyler starts to worry their lives might be in danger with Walt's employers and tries to convince him to give up cooking meth.

    Walter: No, you clearly don't know who you are talking to, so let me clue you in. I am not in danger, Skyler. I am the danger. A guy opens his door and gets shot, and you think that of me? No. I am the one who knocks!
  • Buffyverse:
    • Angel. People say this a lot to the title character; of course they don't know who they're dealing with either.
      Cordelia: You don't know who he is. Oh, boy... you're about to get your ass kicked.
    • Detective Kate Lockley finds a criminal ring is secretly run by demons, who naturally assume she really doesn't know who she's dealing with.
      Head demon: Do you know what walks this city? (Kate shoots him four times; he barely flinches) You have no comprehension! You do not understand what stands before you!
      Angel: A big, ugly drug-running demon, who thinks he is a lot scarier than he is, maybe? Yeah. She knows.
    • And subverted in typical Joss Whedon style.

      Vampire: Oh God, my leg! Ah!
    • Buffy also has the First Evil who says this quite a lot.
      The First: You think you can fight me? I'm not a demon, little girl. I am something that you can't even conceive. The First Evil. Beyond sin, beyond death. I am the thing the darkness fears. You'll never see me, but I am everywhere. Every being, every thought, every drop of hate—
      Buffy: Alright, I get it. You're evil. Do we have to chat about it all day?
      The First: You have no idea who you are dealing with.
      Buffy: Let me guess. Is it...evil?
    • And again in "The I in Team", when Buffy survives an ambush.
      "Professor Walsh? That simple little recon you sent me on wasn't a raccoon. Turns out it was me, trapped in the sewers with a faulty weapon and two of your pet demons. If you think that's enough to kill me, you really don't know what a Slayer is. Trust me when I say you're gonna find out."
    • Another serious case in "Never Leave Me". Spike's 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: Do you have any idea what I'm capable of?
      Buffy: I was in the cellar with you. I saw what you did.
      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.
      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.

    D.A. Clemmons: I suggest you keep your emotions in check, Mr Kent. You obviously have no idea who you're dealing with, here.

  • Played straight most of the time in 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 brought out the girls and booze and got them all drunk.

  • Irenicus in Baldur's Gate II seems irritated any time anyone is foolish enough to try to attack him. In particular: "You dare to attack me here? Do you even know whom you face?" (Then everyone dies.) Being a level 30 mage in a world where level 20 means legendary power (at least until the BG 2 expansion), he can hardly be blamed.

    What the fuck did you just fucking say about me, you little bitch? I’ll have you know I graduated top of my class in the Navy Seals, and I’ve been involved in numerous secret raids on Al-Quaeda, and I have over 300 confirmed kills. I am trained in gorilla warfare and I’m the top sniper in the entire US armed forces. You are nothing to me but just another target. I will wipe you the fuck out with precision the likes of which has never been seen before on this Earth, mark my fucking words. You think you can get away with saying that shit to me over the Internet? Think again, fucker. As we speak I am contacting my secret network of spies across the USA and your IP is being traced right now so you better prepare for the storm, maggot. The storm that wipes out the pathetic little thing you call your life. You’re fucking dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that’s just with my bare hands. Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Marine Corps and I will use it to its full extent to wipe your miserable ass off the face of the continent, you little shit. If only you could have known what unholy retribution your little “clever” comment was about to bring down upon you, maybe you would have held your fucking tongue. But you couldn’t, you didn’t, and now you’re paying the price, you goddamn idiot. I will shit fury all over you and you will drown in it. You’re fucking dead, kiddo.

  • In Worm, PRT Director Tagg explains to Skitter, who murdered his predecessor and who he ordered attacked in her civilian identity, why she can't win against the PRT, and against him in particular.
    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, 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.

    Mandrake: Ming, do not let it have it!
    Ming: Have you lost your senses, conjuror?
    Mandrake: He is not who he seems! He wants to destroy everything!
    Ming: Is this true?
    Mystic/Shiva: All true — and more.

    Ming: No!
    Mystic/Shiva: Give it to me!
