->'''Leonard:''' "You betrayed us for money!"\\
'''Sheldon:''' "I'm a [[WorldOfWarcraft Rogue Night Elf]]; don't you people read [[CharacterAlignment character descriptions]]?"
-->-- ''Series/TheBigBangTheory''

Characters are the sum of their tropes. Sometimes the GenreSavvy even recognize this about themselves. When another character makes a comment about their behavior that fits their character, they will usually respond with something like, "It's what I do."

'''Can be used in several ways:'''
# A comedic "Duh!" moment, which is most often.
# A {{Tearjerker}} when they perform a HeroicSacrifice.
# A villain berating the heroes for [[DidYouActuallyBelieve actually expecting something different]] from them.
# A [[JerkJustifications Jerk Justification]]

An implication with using this line is that characters need to be consistent in their behavior, not just doing whatever is needed for the plot. But don't be too surprised if characters behave in a way slightly different than you expect, as an OutOfCharacterMoment can be the opposite of this.

The underlying implication is that the character doesn't necessarily WANT to do whatever it is they're doing, that it's not a special case just business as usual. It's their nature and they can't help it. Can express a desire for emotional growth, or the lack thereof if "What I Do" is something the character has spent a significant amount of time trying not to do, or angsting over doing it.

Or, in the Type 2 case of a heroic sacrifice, the person being saved is someone who arguably doesn't deserve to be saved. The hero is expressing that it doesn't matter if the victim deserves to be saved; a trademark of someone suffering from ChronicHeroSyndrome. To not be the hero is unthinkable. However, since these heroes are very rarely stabbed in the back immediately after taking the bullet for a nemesis... well, maybe the victim did deserve to be saved. This situation lends itself to many a HeelFaceTurn.

Also see TheFarmerAndTheViper, which is when a villain makes a hero pay the price for not realizing this.

* Rika Shiguma from ''LightNovel/BokuWaTomodachiGaSukunai'' is a very perverted character, and for the most part is not afraid to hide her interests from other characters. She will often also shout {{Unusual Euphemism}}s such as [[http://www.youtube.com/watch?v=zGRxJmVbii4 "Universe!"]] and [[http://www.youtube.com/watch?v=r-beXhtVekY "Excalibur!"]], and tries to introduce other members of the Neighbors club to her interests such as BoysLove, video games, or mecha on mecha porn.

And it's never going to change.

The about-to-be-killed TheObiWan gives him a TheReasonYouSuckSpeech, pointing out that such an event is mentioned nowhere in the Bible or in any prophecy, and the BigBad's entire plan is doomed to fail.

[[folder:Literature]]
* Lighter Than Some, a Covenant Engineer in the {{Halo}} novel ''Contact Harvest'', was ridiculously friendly. When pressed by a human-made AI on why he was helping her, he would simply reply "Lighter Than Some," which she figured meant "I help because that is who I am."
** Helps it was also [[spoiler: TheAtoner because it was the first Covenant to kill a human]]
* In Stephen Donaldson's ''[[TheMirrorOfHerDreams Mordant's Need]],'' one of the heroes keeps getting into duels with the BigBad's chief swordsman. He pauses to ask the swordsman why he doesn't simply overthrow the BigBad (who is portrayed as an essentially impotent dupe of his supposed underlyings.) The swordsman replies with this trope.
* Evil Lord Harry Dread, from ''[[Literature/{{Discworld}} The Last Hero]]'', allies himself with his enemies the Silver Horde for one last adventure. [[spoiler:Later on he betrays them, but they don't hold it against him, because its [[GoodOldWays tradition]]]].
** Another Discworld example is Dr. Hix, the head of the department of Post-Mortem Communications, in ''Making Money'' and especially in ''Unseen Academicals''. It's his job to be "evil" because of his department, so whenever he does something underhanded or says something nasty he points this out, often indicating his official skull ring. (Most of the things he actually does are [[PokeThePoodle poodle-poking at worst]].)
** Lord Vetinari is also known to occasionally remind people that he's the Tyrant when they protest that he "can't do that!"
** In ''Discworld/{{Sourcery}}'', Rincewind asks Abrim "''You'' employ the slavers?" and Abrim says "I am the [[EvilVizier vizier]] after all. It is rather expected of me."
* In the fable "The Scorpion and the Frog," the titular scorpion asks the titular frog to carry him across a river. The frog is afraid of being stung, but the scorpion reassures him that if it stung the frog, the frog would sink and the scorpion would drown as well, so that wouldn't be logical. This sounds reasonable to the frog who agrees to take the scorpion. But halfway across the river the scorpion stings the frog anyway, and as they both sink the frog asks why the scorpion did it, and the scorpion replies:
-->"It's neither reason, nor logic. I'm a scorpion; it's my nature."
*** Alternate quote from the scorpion:
--> "I've never NOT stung."
** Averted in the Clan Scorpion {{Splatbook}} for the ''LegendOfTheFiveRings'' role-playing game, the scorpion's reply to the frog is, "I can swim."
** [[TheFarmerAndTheViper A similar fable]] involves someone bringing a snake inside, or putting it inside his shirt, to warm it up, only to be bitten by the snake. In some variations the snake talks, and replies to the human's surprise with "You knew I was a snake when you brought me in." [[ReptilesAreAbhorrent It doesn't reflect very well on snakes]].
* In ''Literature/CodexAlera'' the Vord Queen explains this as her reason for trying to destroy Alera. It appears to be a genetic imperative for the Vord to destroy all other species. She also offers the same excuse to [[spoiler: [[ChronicBackstabbingDisorder Invidia]] for betraying her, explaining that not betraying her just isn't in her nature, and she's welcome to keep working for her.]]
** Discussed with regard to [[spoiler: Invidia, too, to the effect that she can be counted on to betray her rescuers]].
* In the ''Literature/EnchantedForestChronicles'', Telemain is often asked why he experiments with magic or wants to study the magic of wizards. As a magician, he always insistently gives this as his reason.

** Episode "Revelations": O'Neill agrees to help the Asgard while Hammond and Carter still argue over it with the explanation: "It's what we do, isn't it?"
* ''{{Scrubs}}'' (JD is talking with a terminally ill patient about what death is like, which annoys Dr. Cox. When he leaves the room in a huff, the patient tells JD, "It's fun to annoy him, huh?" JD replies with a touch of deadpan, "It's what I do.")
** Turk has been known to say this in more than one occasion: "Well you know I do what I do what I do what I do."
** One episode featured an online review system for doctors, which was used as a sly dig at fan reactions to the show. With Turk he is shocked at how people dislike his catch phrase.

* ''{{CSI}}'': Ecklie, former less-competent CSI and now head administrator, has always been a thorn in the team's side, but as administrator he gets actual moments of respect, like this one: Catherine had a memory card of evidence photos stolen from her and been grilled earlier by Ecklie for it; the photos appear on the television news.
--> '''Ecklie''': "I'll have our public information officer contact his counterpart at the station. We'll also call Judge Anderson and get a warrant for the memory card, any copies, and the name of their source."
--> '''Catherine''': ''(surprised)'' "Thank you, Conrad."

* In ''WebVideo/YuGiOhTheAbridgedSeries'', Kemo has two main traits. The first is saying anything about his hair. (It is very strange, even for anime hair.) The second is using the phrase "Attention, Duelists!" to begin every line of dialogue that he says. This is because he works as a tournament announcer, so it makes sense. But one time, when he was alone with Seto Kaiba and used the CatchPhrase, Kaiba questioned why he said it. Kemo responded by quoting this trope by name.
