* While talking to Pritchard at Sarif Industries, one of the offhand comments he'll make during the conversation is "Jensen, I know your body's been going through a lot of changes lately, but you didn't become a woman. Stay out of the ladies restroom." The unexpectedness of it was a real treat.
** It's a ShoutOut to the first game. When you first visited the [=UNATCO=] [=HQ=], you could go into the woman's restrooms, where a woman using it would chide you for being in there. Manderley would later chew you out for being in there during the first debriefing.
** Even made more funny when you were sneaking into the Lady's Restroom to listen in on their chat only to then get berated with that comment.
* [[VideoGameCrueltyPotential You can sucker punch anyone]] (excluding certain zones). That's right: ''anyone''. [[http://www.youtube.com/watch?v=zYpuzHyEY8Q A small taste]].
** It's hilarious when used ''in context''. The lady outside your apartment who scorns you for having augs? Cold cock her.
** If you perform a non-lethal double takedown behind two enemies, Jensen could end up kicking one of them in the back of the knee and quickly grabbing the second person and positioning them. The first person will stand back up and take a swing at Jensen, but ends up knocking out the second person. Then Jensen finishes the first person off with a few body shots and a hard throw to the floor.
** Equally hilarious is the variant Adam does when he's facing someone. No special moves. He just hauls off and decks them.
** Another one, hilarious in its brutal simplicity compared with other, more complex ones, is that Jensen just grabs the first target and headbutts him/her, then turns, grabs the second one, headbutts him/her, and walks on.
** Several of the two-person non-lethal takedowns start by your targets attacking Jensen first and him expertly countering their assaults. However, since you can do it on any two people, you're just as likely to counter two hardened security officers as [[http://www.youtube.com/watch?v=MMl-4BndT20 street prostitutes]].
** [[BondOneLiner What a]] [[http://www.youtube.com/watch?v=90qaByv3c1k&feature=related shame]].
** One lethal take down has Jensen ''picking up'' one of the enemies, and ''dropping him onto the other'' [[http://www.youtube.com/watch?v=DCcGmpuG5ew&feature=player_detailpage#t=187s followed by a quick stab through both]]. BloodyHilarious at its finest.
** You could perform feats of Franchise/{{Predator}}-like badassery just by generally cloaking up and then performing a takedown, or sometimes the multiple takedown. Its downright hilarious to see yet another guy look around for you, unsure where you are, and perform ''yet another'' takedown, uncloaking in the process. It might be highly energy consuming but it's worth it.
** The ultimate example of Jensen's epic-level face punching prowess is that, during the boss battle with Namir, with the right timing the player can trigger a takedown and kill him with a single punch to the jaw.
* Jensen's [[http://www.youtube.com/watch?v=Y414Q7vVgYU&feature=player_embedded dance moves]].
** Somebody else has suggested muting that video, and substituting [[http://www.youtube.com/watch?v=oECIKVaz5rc this song]] from Film/{{Orgazmo}}.
* "Malik? Remind me to never piss you off."
** From the same mission, if you kill [[spoiler:Lee Hong]] rather than do as Faridah asks:
-->'''Malik:''' [[WhatTheHellHero What the hell]], Jensen, I never said anything about killing him!
-->'''Adam:''' Would you believe me if I said it was an accident?
** Or if you knock him unconscious before talking to him:
-->'''Malik:''' Jensen! [[WhatTheHellPlayer Why did you do that]]? How exactly do you plan on [[spoiler:getting a confession]] out of someone who's unconscious!
-->'''Adam:''' Shit happens. [[BlatantLies I'm sorry]].
* Omega Ranch is a secret facility of secret facilities. It's patrolled regularly by guards, robots, the best electronic security that you can get...and they still get spammed by Nigerian Scam emails.
** Possibly due to how the security team keeps downloading animal porn and putting it on one of the scientists computers to mess with him.
* After you hack into Pritchard's computer, you will see his email regarding to his rejected drama script from Picus TV. The producer doesn't like his script about a super hacker who saves the world via desktop (like himself) and suggests that characters such as vigilante ex-cops who fight crime while trying to maintain their morals (like Jensen) are more popular. No wonder why he doesn't like Jensen that much.
* In [[spoiler:the Picus Sub-Basement]], one employee complains via email that the [[spoiler:partially holographic statue of the MJ-12 logo]] out front is a waste of money that looks like something out of a Bond movie. Another employee simply retorts that "[[RuleOfCool It looks cool]]."
* On a side mission to find out about the death of Malik's friend, Adam Jensen has to meet with someone called Anonymous X and say the phrase [[SpySpeak "Death and Life have their determined appointments."]] To which he would reply [[SpySpeak "Riches and honor depend upon heaven."]] Adam comments it sounds [[LampshadeHanging like a bad spy movie]] but the real gem is when you meet with Anonymous X. Adam can be professional and say the phrase, he can be impatient and just demand Anonymous X to give Adam what he wants or he can be dismissive and the conversation goes as such:
-->'''Adam Jensen:''' Something, something, Death and taxes. Confucius.
-->'''Anonymous X:''' What? Wait, that - that's not it at all! That's not even close!
-->'''Adam Jensen:''' Does it matter?
-->'''Anonymous X:''' Of course it matters! Otherwise, how am I supposed to know you're- You were supposed to say 'death and life have their determined appointments'! Then I say 'riches and honor depend upon heaven'!
-->'''Adam Jensen:''' Okay. 'Death and life have their determined appointments'.
-->'''Anonymous X:''' Riches and hon- oh nevermind! You ruined the whole thing!
** The best thing about Anonymous X is his [[ImageBoards #Chan]] hat.
*** As soon as Malik first says the name "Anonymous X" she immediately follows with "I know, I know..." as if saying "Yes, ''that'' Anonymous".
** The real kicker is the way Jensen says the "Something, something" line. Which is to say that he delivers it with his usual dead-serious GutturalGrowler tone.
** Even more fantastic; [[TakeAThirdOption take the third choice]]:
-->'''Jensen''': Nice hat. I'm here for Evelyn's autopsy report.
-->'''Anonymous X''': What? Are you mad?!
-->'''Jensen''': No, just impatient.
** The capstone to the entire thing, though, is to pay off Anonymous X when he asks for his money, and then knock him out and take your cash back. There's no real reason to do this (you can just refuse to pay him and walk away over his protests) except ''because you can.'' Hell, it's arguably just as entertaining to refuse to pay.
-->'''Jensen''': Word to the wise. If you're going to extort money from someone, don't wait until after you've given them what they want.
* Finding a "Final Fantasy XXVII" poster in Pritchard's office and the [[spoiler: Omega Ranch]] was a nice bit of self-referential humor from SquareEnix.
** Amusingly in [[spoiler:Omega Ranch]] the posters are in the barracks room of some soldier. That guy must be a serious geek when he isn't guarding a top secret facility for an evil conspiracy.
* After Pritchard relays Jensen a message from [[spoiler:Zeke Sanders]], Jensen takes the opportunity to correct Pritchard's pronunciation of the word "[[spoiler:[[ForeignCussWord cholo]]]]" in the most condescending tone possible.
* Just this:
-->'''Gang member''': Rest in peace, Big Rizzle.
-->'''Jensen''': ''(completely uninterested)'' Yeah, RIP.
* In a brilliant case of TheDevTeamThinksOfEverything, you might feel so inclined to break into all the officers at Sarif HQ to steal anything you can, especially when you get asked to investigate some offices. Well do that, then when [[spoiler: you revisit the building later on,]] be sure to check your office e-mails. [[spoiler: You discover that there has been an [[TakeThat office bandit']] going around stealing everything, with wild accusations flying around.]] You get asked to investigate but of course you find [[FridgeBrilliance no leads.]]
* Overhearing the argument between Mei and her manager at the Hung Hua Hotel will get you this:
-->'''Mei''': Tell your customers to get augmentations themselves and go fuck themselves!
-->'''Manager''': [[ScrewYourself I'm sure some of them already have.]]
* On the sidequest to rescue a kidnapped prostitute in Hengsha, Jensen has to talk to an informant who demands a bribe. If you refuse, he'll point out that you can't expect to just knock him out, as [[LampshadeHanging he doesn't just conveniently carry that information on him]]. If you do knock him out....[[DangerouslyGenreSavvy he really won't have that information anywhere on him.]] On the other hand, after you pay him, there's nothing stopping you from knocking him out and getting your money back.
* At the Omega Ranch, you can read elaborately-worded emails sent by an angry scientist complaining that someone keeps putting animal porn on his computer. He requests security help him catch the perpetrator. When you get further inside the Ranch, however, it becomes apparent that the security guards are the ones pranking him. [[TheOffice They also did something with his stapler.]]
* Trying to use the Social Enhancer on [[http://www.youtube.com/watch?v=E75ln7u_5PM Malik.]]
* Absolutely anything involving vending machines or refrigerators. Especially [[http://www.youtube.com/watch?v=0l3wOT9cSg4 this]].
** [[http://www.youtube.com/watch?v=ymtCllSsfcg Acknowledged]] [[AscendedMeme by the dev team!]]
* [[http://www.youtube.com/watch?v=-A6eeeq_2TE&feature=player_embedded Adam Jensen walks into a bar...]]
* [[http://www.youtube.com/watch?v=8Xd0LO04tis "Nice sunglasses. But it's night-time, you dig?"]] (Note, the music doesn't actually play in the game itself.)
* When Pritchard calls Jensen to bug him about an early mission if you've been roaming around instead of, you know, completing the objective, Jensen formally calls him "Francis".
* When Jensen meets a corrupt cop (posing as a hired killer to murder a witness), one of the responses is pretty funny:
-->'''O'Malley''': Were you followed?
-->'''Jensen''': [[SarcasmMode Yeah, by a clown and a midget for a while. But they eventually met the bearded woman they were looking for near a coffee shop and we went our separate ways.]]
* One of the emails you read on the Omega Ranch is from the office administrator, who notes that people have been using equipment as benches due to a lack of chairs. After a long winded explanation of how the tensile strength is not enough to support a human's weight, he ends "In short, stop breaking shit with your fat asses. XOXOXO, The Management."
* Some of the Picus news crawls are hilarious.
-->''Wisconsin cheese-eating champion dead of lactose intolerance.''\\
''"[[SoYouThinkYouCanDance So You Think You Can Dodge Traffic]]" was pulled from the network today.''
* Anyone you end up bribing or otherwise paying money to can be immediately cold-cocked in the face to get your money back. You can even bypass the entire conversation/sidequest with Brian Tindell by simply rolling up to him while he's sitting there and walloping him in the nose, then taking the recording from him.
** Take down the two drug dealers ''before'' you talk to him, then agree to help him. When Brian tells Adam the names of the drug dealers, Adam's response is along the lines of: "Wait, ''those'' guys? Yeah, they're actually out of the picture. They'd... already stepped on the wrong toes."
* When Tong contacts you directly though your personal communications link:
-->'''Jensen:''' Tong! How did you get my frequency?
-->'''Tong:''' [[ShoutOut Ancient Chinese secret.]]
** Tong in general is hilarious when he's playing dumb with Jensen...
-->'''Jensen:''' I'm looking for a man named Arie van Bruggen.
-->'''Tong:''' Never heard of him. What he do? Steal your girl? Owe you money?
** Or...
-->'''Jensen:''' Vasili Sevchenko.
-->'''Tong:''' Never touch the stuff.
* Windmill's apartment in Hengsha has a bunch of post-it notes stuck to his workstation. Several of them have girls' phone numbers on them... along with doodles of the [[http://knowyourmeme.com/memes/forever-alone Forever Alone guy]].
* Everyone can get Jensen's frequency, from random hackers to crimelords. And he's ''always'' surprised.
* In the Picus sub-basement you can find an email regarding their plans to discredit someone capable of exposing [[spoiler:Taggart's ties to Purity First]] by forging and leaking an incriminating video. Said e-mail asks the recipient for input as to what the video will contain: "[[Creator/ParisHilton home porno]] or [[Creator/MelGibson racist drug-induced violent episode]]?"
* What could pretty much count as the abridged version of ''Deus Ex Human Revolution'': [[http://www.google.co.za/url?sa=t&rct=j&q=adam%20jensen%20the%20augmented%20people%20person&source=web&cd=1&cad=rja&ved=0CCkQtwIwAA&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DCvqYb4LNkB0&ei=aILuUczdF4yShgfrpYDICg&usg=AFQjCNEIHQCgHbL6EmVOGEl_slspWHziyg&bvm=bv.49478099,d.d2k Adam Jensen, augmented people person.]]
* When in the [[spoiler: FEMA internment camp]] you can find a guard with the key code for his quarters in his pocket. You will also find a note from the IT guy announcing that after all the times that guy's forgotten his code, he's getting the damn thing written down so the guy will stop pestering him, no matter how many security protocols it breaks.
* Failing the dialogue with Wayne Haas in the Police Department gives you a two-way snark exchange between Jensen and his boss.
-->'''Jensen:''' Hey, uh, boss. How badly do you want that report?
-->'''Sarif:''' If you're considering multiple homicides to get it, I suggest you back off and look for a less, uh... conspicious way in. From outside the building.
* Fan-run Deus Ex Wiki has a [[BarkleyShutUpAndJamGaiden funny idea]] of explaining [[http://deusex.wikia.com/wiki/File:1382237715858.gif Typhoon Explosive System]].
