As far as human organs go, there is the common idea that no one knows exactly what the spleen does.
Therefore, a common sight in fiction is that either the spleen is a completely useless part of the human body or it serves some sort of encumbering function. Often Played for Laughs, especially with the implication that damage or loss of the spleen is trivial and harmless.
Along with the fact that it's seen as useless, the spleen is often portrayed as a convenient place to get hurt/injured in a fight, possibly because it is somehow considered funny.
In fact, the spleen plays a very important role in the lymphatic and immune systems. It is easily ruptured by blunt or piercing impact and is very difficult to repair (doctors say that it has the natural consistency of a blood-soaked sponge). If severely damaged, often it must be removed surgically or the person in question is likely to bleed to death; once removed, the person has to take care to avoid bacterial and protozoan infections (to which they become more susceptible). A fairly comprehensive treatment of the subject is covered in a blog entry by Dr. Scott.
- Inverted in an ad for Batman: Arkham City, in which Harley Quinn has a voiceover similar to theme park's "keep hands in car at all times" announcements. Harley denies liability for injuries to a series of body parts, including "spleen or other vital organs". The spleen may not be useless, but it's not a vital organ either: you can survive without one, else removing a damaged spleen would not be an option.

- In the novel The Venom Factor, Venom states that when he finds whoever is responsible for the murders (that Venom is being wrongly accused of) he will eat his spleen. Spider-Man comments that this is an odd choice of organ to target and that Venom likely doesn't even know where someone's spleen is.
- Comes back in the Sinister Six Trilogy where Spider-Man casually jokes about Venom wanting to eat his spleen. He speculates that it's not specifically the spleen he's after, they both just think it's a funny word.
- Averted in the Stardoc series — or at least for the Jorenian race, for whom it's a vital organ.
- Star Wars Legends:
- New Jedi Order, of all things, contains a notable aversion of this trope.

- In Wraith Squadron, perpetually injury-prone (30% mechanical and counting!) pilot Ton Phanan is hit by a small piece of shrapnel, which happens to penetrate his spleen. Fortunately, he is soon in the hospital and presumably picks up another replacement cybernetic in the process.

- A few Bodies of the Week from the franchise have succumbed to bleeding out after a bludgeoning attack or collision ruptured their spleen.

- Married... with Children: In a two-part episode, Bud borrowed money from a loan shark named Vito Capone. ("No relation", he says) When it seemed he'd not be able to repay, Vito said something about extracting Bud's spleen. When Bud asked he'd be able to live without a spleen, Vito said he could. (Not that it matter, since it'd not be the only organ he'd lose)
- In a parody of "Ain't Got No", a song from Hair, a line is "Got my spleen (whyever)".
- There's the line "My spleen just doesn't matter" in "Weird Al" Yankovic's song "Pancreas."

He only cares about his pancreas, and seems to equally not care about all of his other organs.
- On Sawbones episode "The People vs. The Spleen", Justin makes a case that the spleen is a useless organ, based mainly on the fact that it took most of history for physicians to figure out what it does, and that this information never became public knowledge.

- The Order of the Stick:

A character mentions losing their spleen in a fight, which at first seems like just another case of Inherently Funny Words, but they later mention in passing that they will need to take medicine for the rest of their life, and have been honourably discharged from the army.
- Irregular Webcomic! :
- One of the Pyramid magazine strips, which can be found here, features a critical hit chart aimed at PC's. "Spleen" was labelled "Susceptible to Infection", which is a nuisance in a fantasy setting (more so in Low Fantasy), but given how many of the other organs are labelled "Death", "Paraplegia" or "Crippled", Ruined Spleen Guy is probably getting off lightly.

So, hypothetically beating a bystander in the spleen could have healed him.
- Used in Exiern, here.
King Urtica: Besides, in this business it can be useful to work with someone who is heartless.
Olivia: I am only literally heartless. I am generally a very passionate person.
Urtica: I meant it literally. I've lost a lot of right hands to blades.
Olivia: I will die if poisoned, crushed, drowned, dropped from a great height, or stabbed in places other than my heart.
Urtica: Perhaps, but this is political intrigue at the very highest of dramatic levels. No-one ever aims for the spleen.

- There's a Running Gag in Darths & Droids about an organ called the splanch, not that humans have it, apparently. It must be some kind of spleen IN SPACE! At one point, when the Game Master mentions a "sleen" (a lizard), Jim claims it's the organ behind the splanch.
- In an episode of Beavis and Butt-Head, the duo try to get money by suing people for injuries they supposedly obtained from people. Near the end, Beavis is hit by Tom Anderson's car.

Then returns to his body. Moral of the story is that the spleen is not a useless organ. Subverted in a final scene showing the Flea's spleen return to his "home"; he does nothing but watch TV.
- Averted in Ozzy & Drix, where Ozzy dispatches one villain by luring him to the spleen and describing its functions. Said spleen is effectively a Turbine Blender.
- Dave the Barbarian:

- Also averted before birth. Up until the fifth month of gestation, when bone marrow develops, a human fetus's blood cell production occurs mainly in its spleen.
- A French idiom for "running very quickly" is "courir comme un dératé" ("running like someone without spleen"). It comes from the old belief that the spleen is useless beside causing side stitch during the effort, thus losing the organ wouldn't have any detrimental effect but would make you more athletic.
