Barbossa: Why thank ye, Jack.This is where a human character and an animal companion share a name for some reason. This can work one of two ways:
Jack Sparrow: You're welcome.
Barbossa: Not you. We named the monkey Jack.
Jack Sparrow: You're welcome.
Barbossa: Not you. We named the monkey Jack.
- "We Named the Monkey Jack": The animal was named after its human counterpart, either to honor a fallen comrade or (more likely) as a subtle Take That! against an enemy.
- "We Named the Dog Indiana": The human was named for the animal, or takes a nickname (or false identity) from the name given to a beloved pet or other animal companion.

Anime & Manga

- Nanami the cow from Revolutionary Girl Utena. Not only does Anthy name a cow Nanami, in the episode "Cowbell of Happiness", Nanami the human turns into a cow. It's that kind of series.
- She later names a chicken Nanami, as well. It's strongly implied that all Nanami's animal-related issues are a result of Anthy's passive-aggressive retribution for her cruel prank in episode 3. She is a witch, after all.
- Kouya in The Twelve Kingdoms renames his youma (demon) "Rokuta" after the human name of his first (and for a long time, only) friend.
- Subverted in Wolf's Rain. After feeding a stray dog, a girl named Leara meets a boy who says the dog's called Toboe. She's confused when he later calls himself Toboe. He claims this is because he and the dog are so alike. It's probably not spoileriffic to reveal that the dog is actually a wolf, and that the boy and wolf share the same name because they are one and the same. When Leara finds out the truth she freaks out, to his dismay.
- Ichigo of Tokyo Mew Mew names her fluffy mascot, Masha, after her boyfriend, Masaya.

After the rest of the teams have emerged from cryostasis, he tells Ayu that he regretted choosing the names almost immediately, because he knew he would probably outlive them again.
- In Nisekoi, Marika Tachibana's parrot is named Raku-sama, after the main protagonist, Raku Ichijou, whom Marika is in love with. She's teaching the parrot all sorts of kinky stuff to say, making her all the more a creepy stalker.

- In Detective Conan the estranged wife of detective Kogoro Mouri has a cat called Goro. It takes even Shinichi/Conan a while to realize that there is just one syllable difference. And since they separated before the series began, but she acquired Goro way later, it's also clear who was named after whom.
- The Team Pet in Yona of the Dawn is a little squirrel named Ao. He originally belonged to Sinha, who named him after the previous Blue Dragon, who was his mentor and father figure. This leads to an amusing moment in the manga when Yona asks where Sinha learned swordsman ship. Sinha replies "Ao" and Yona, not knowing the backstory, imagines the squirrel holding a knife.
- Saito in volume 9 of The Familiar of Zero purchases a horse which he names after Louise. She quickly forces him to change it.

- The ventriloquist Jeff Dunham:
Jeff Dunham: I named the dog "Bill" because I got him when Clinton was in office, and as a puppy, he was humping everything.
- An old joke (replacing the actors' names as appropriate) concerns an aspiring screenwriter sending his work to a famous director for appraisal. Some time later, he runs into the director walking his dogs, and asks him about it. The director replies that he showed it to Stewart and RDJ, and they loved it, damn near devoured his script while showing great enthusiasm. The screenwriter is ecstatic, until one of the director's dogs starts humping the other, at which point the director yells "Stewart! You get off RDJ right now!".
- In Cerebus the Aardvark, Cerebus becomes a shepherd and names one of the sheep "Elrod". It is unclear whether he's doing it because the sheep annoys him like Elrod used to, or if (after all these years) he misses Elrod (as well as his other old acquaintances). Outliving everyone you knew can have that effect on you.

- In the Gargoyles comics, it's revealed that Mary and Finella name their horse after Magus. "Something about his face," Mary says.

- Marilyn Rexroth in Intolerable Cruelty names her dog Howard after one of her ex-husbands.
- Aragorn's horse Brego in The Two Towers is apparently named after an earlier king of Rohan.

- In one of the unused scripts for Highlander: The Source, Duncan has a monkey named after his cousin Connor.

- In one of the The Witcher novels, Friendly Neighborhood Vampire and Technical Pacifist Regis names the party's donkey "Drakul". Jaskier, who is narrating the story, says that Regis refused to explain the name, saying its "an untranslatable play on words". One possible explanation is "dracul" is Romanian for dragon or devil, which would count as a Genius Bonus since it's also the origin of the word Dracula.
- In the Doctor Who Expanded Universe novel The Last Dodo, the Doctor names the titular bird Dorothea. He doesn't explain why, but Dorothea Chaplet was a former companion, usually called "Dodo".
- In Douglas Adams's unfinished Dirk Gently novel The Salmon of Doubt, Dirk is hired to discover the name of a client's late husband's small dog, which turns out to be "Kierkegaard"; the guy was writing a biography, and sometimes just really needed an excuse to yell "Shut up, Kierkegaard!"
- As pets can seem a lot like people when you're nine, Peter Hatcher's naming of his dog at the end of Tales of a Fourth-Grade Nothing might count. He named his new puppy "Turtle", after the pet turtle his little brother had swallowed.

When Sutro's inactivity leads to the city being invaded by the British, Clemens comments that the shared name is actually more insulting for the dog.
- In The Rose Years, Almanzo Wilder names both a mule and a colt after his older brother, Royal. Roy the mule is probably meant to be a joke, as his wife named their other mule after Nellie Oleson, her childhood rival, but the colt was named "Royal" because he'll be the crown prince of the Wilders' livestock, just like Almanzo's brother was the crown prince of their family.
- In the Charlie Parker Series, Parker names his dog Walter after NYPD friend Walter Cole, although his reasons are unclear and it seems likely that the author never actually intended this trope, but simply forgot when naming the dog that he already had a character named Walter. The trope still applies retroactively however, and Walter Cole is never particularly pleased about having a dog named after him.
- Maikel Staynair in the Safehold series has a pet cat-lizard he named after his late wife. Only after that did he and his children realize that the cat-lizard was a male. Since the Staynairs' late matriarch had the kind of sense of humor that would've considered this hilarious, they never bothered to try changing the name.
- In A Song of Ice and Fire, Daenarys Targaryen named her three dragons after her dead husband Drogo and her dead brothers Rhaegar and Viserys.

- On Boy Meets World, Shawn has a pig he calls Little Cory.
- In El Chavo del ocho the kids adopt a puppy and promptly name it "Ramoncito" after Don Ramón the resident slacker. The kids doesn't mean ill, but of course the human namesake isn't very flattered. Mostly because when the kids justify their reasons by pointing how cute the physical features of Don Ramón look in the puppy, the "homaged" only sees the Stealth Insult.
- Bobby on Cougar Town gets a dog who he names Travis, which is also the name of his son. He later explains he names everything he loves Travis. To avoid confusion, he refers to the dog as D.T. which stands for "Dog Travis".
- Doctor Who:

- In "The Girl Who Waited", Amy, trapped in the Two Streams facility for thirty-six years, gets a Companion Cube robot that she has literally disarmed and painted a smiley-face on for company, and names it Rory. It's initially taken as a sign of how emotionally distant to Rory she now is, she doesn't address him by name. Later however when Old Amy talks to Young Amy, Young Amy points out/reminds her why she named it Rory, instead of "the Doctor" or after her favorite cat. It's because Rory is the love of her life.
- There's an episode of Father Ted where Dougal gets a rabbit, and initially wants to name it Ted, then suggests "Father Jack Hackett" as an appropriate name. So it is played with, but they end up calling it Sampras, which is a sort-of example, since Pete Sampras is obviously a human, but equally obviously not a character on Father Ted. Dougal gives his logic in this as "the obvious rabbits-tennis connection."
- In Fawlty Towers, Manuel's pet rat ("No rat, ees Siberian Hamster!!") is called Basil.
- In Gordon Ramsay's UK series The F Word, he has a habit of naming the various animals he raises in his backyard after other celebrity chefs.

And Janet Street-Porter once got Gordon back by naming the horse she was going to have slaughtered for its meat after him.

- In the first season of Heroes, Chandra names his pet lizard after his son, Mohinder.
- One of Wilson's exes in House owned a dog with him that constantly peed on their rug; she blamed House for wrecking their relationship and subsequently named the dog Hector because "Hector Does Go Rug" was an anagram of "Doctor Greg House". House thought that connection was tenuous at best too.

- S2 Ep15, "Caught On Tape": Kate names the dog of the killer, Tony, even though it's a girl. This leads to a humorous scene where Tony is listening in on Kate and Abby talking about whether Tony likes them, how cute Tony is, and how maybe they could share Tony.

- In the Smallville episode "Krypto," Lois Lane spends much of the episode referring to the dog as "Clarky" because, as she says, "he's annoying and I can't seem to get within ten feet of him without getting sick" which was, of course, actually a dig at Clark. She later suggests that Clark change his name to avoid confusion.

- In Monkey Island 2: LeChuck's Revenge, Elaine has named her dog Guybrush, for a series of unflattering reasons.
- Mostly because this is a Shout-Out to Indiana Jones.

- Ghost Trick: Sissel was named after Yomiel's dead fiancee, which provides a neat explanation for his Gender-Blender Name.
- Final Fantasy: Crystal Chronicles: Echoes of Time, in the post-game, has a cat named Sherlotta, after one of the main characters. Well, kind of.
- In The Legend of Zelda: The Wind Waker, a family on Outset Island names their pet pig after you.

- Also occurs in Twilight Princess, where the cat owned by Beth's family shares Link's name. This makes no sense, until you remember the hilarious schoolgirl crush that Beth has for Link.
- Shin Megami Tensei: Devil Survivor 2 has Jungo Torii name a cat he finds "Jungo" because it's easy to remember. It gets confusing very quickly.

- In a Hakuouki drama CD, Okita takes in a stray cat and, because he's a troll, names it "Toshizo" after the Shinsengumi's vice-commander Hijikata Toshizo. Comedy ensues when Kondou overhears Okita, Nagakura, and Saito discussing the feline Toshizo's penchant for stealing food, sneaking into people's beds, and siring children around the neighborhood; the misunderstanding that results is not helped by the fact that Saito can't bring himself to use Hijikata's given name even to address a cat, and instead calls the cat "Vice-Commander" as well.

Joyce has an unrequited crush on Danny. Still mindwiped and unable to remember her prior life, she and new BF Walky get a dog. Named? Daniel.

Examples of Type 2:
Anime & Manga
- In GUNNM, main character Gally is named after a cat that Dr. Ido owned, which had died a short time before he found her. She's not happy to hear this. Of course, in the U.S. version, the cat's name is Alita instead. Either way, part of the reason she's not happy about it is that the cat was male.

Strangely, this is later inverted into Type 1 when Yukimi gets another cat after Yoite dies and, unconsciously influenced by the traces of his memories of Yoite(the person, not the first cat), names it Yoite. And in the end it's subverted when everyone regains their memories of Yoite and Yukimi renames the cat "Yoi".
