Judge: In that case I sentence you to a lifetime of horror on Monster Island. (to Lisa) Don't worry, it's just a name. [Cut to Monster Island; Lisa and others are chased by lookalikes ofMothra, Rodan and Gamera] Lisa: He said it was just a name! Man: What he meant is that Monster Island is actually a peninsula.
In "The PTA Disbands", the PTA most emphatically does not disband (though at one point, a guy mistakenly believes it did, panics and jumps out a window. And jumps back in when informed of his mistake). The episode got its title because writer Jennifer Crittenden thought that that was the worst thing that could possibly happen to a school.
Lampshaded in "'Scuse Me While I Miss The Sky", with the Deadly Meteor Shower; people are apprehensive about this name, until Lisa explains that it was named after its discoverer, Professor Artemis Deadly - who was killed in the shower of 1853.
And in "The Color Yellow," Bart learns that the Underground Railroad was neither underground nor a railroad, and wonders why they didn't call it "the Above-Ground Normal Road."
Nelson and Bart go to the cinema to see a film named "Naked Lunch".
Nelson: I can think of at least two things wrong with that title..."
"Homer vs. the 18th Amendment": Homer's actual dispute is with a city statute and the 21st Amendment, ending national Prohibition but allowing local jurisdictions to continue to ban alcohol, by proxy.
Fry: "Philip J. Fry, the Original Martian." Lies! Every word of it! He wasn't original, he wasn't a Martian, he wasn't Philip J. Fry, and since when is he a "The?" Bender: You're twice the "The" he ever was!
The Cave of Hopelessness. Named after Reginald Hopelessness, of course.
Who, in a similar gag to The Simpsons one above, was the first man to be eaten alive by the Tunneling Horror.
The episode "Fun on a Bun" is actually a big Tear Jerker.
In the Portuguese dub, apart from very poor acting and especially poor translation, all of the episodes are named in the most generic, unfunny and misleading ways possible. For example, "Jurassic Bark", "The Lesser of Two Evils", "The Cryonic Woman", "Teenage Mutant Leela's Hurdles" and "Roswell That Ends Well" (that's five different episodes!) are all renamed "Back To The Past", and only the latter has any time-travelling.
South Park has the song "Kyle's Mom Is A Stupid Bitch In D Minor," which actually isn't in D-minor.
For Aqua Teen Hunger Force, the title of the show itself. The show it is about a group of Anthropomorphic Food. It has no focus on water, none of the main characters are adolescents (or have any confirmed age). The hunger is only slightly relevant, due to them being food, but the fact that they are edible is rarely brought up. The force part was relevant for the first three episodes as a plot to simply get the show airing, as the actual premise of the show would sound ridiculous otherwise.
Whisper in Shattered Glass is LOUD! Mind you, it isSG. Of course, since the Decepticons are not only good but kind of foppish in the SG universe, this is definitely meant to be an ironic thng.
Speaking of Shattered Glass, the good/evil alignment flip means some of the Obviously Evil names wind up on good guys, and the other way around. First Aid, Defensor? Bad. Sinnertwin, Demolishor, Rampage? Good.
In the G1 episode "Enter the Nightbird", the character who needs help jumping up a cliff is the guy named Cliffjumper.
Bluestreak is silver, and not blue. Ironically, the Diaclone toy he was redecoed from was blue, and his packaging art showed him as being blue. Due to trademark problems, he was renamed "Silverstreak" in the 2000's, which fits better. But his thing is that he never shuts up; he talks a blue streak. "Silverstreak" just describes his color and implies that he's fast.
In Animated there are the Jet Twins, Jetfire and Jetstorm, neither of them can fly, in fact none of the Autobots can truly fly. (Some of them, like Prowl have Jetpacks, but the Twins don't) The explanation (Read- Handwave) is that they were pilots before the war.
SpongeBob SquarePants: Neither the eponymous SpongeBob, nor his pants, are actually square. He and his pants are rectangular prisms composed entirely of rectangular faces.
Also, Squidward is an octopus, not a squid (Taken a bit further that he has 6 tentacles, not 8).
In the Disney film The Great Mouse Detective, Padraic Ratigan actually ISN'T a rat; he's just a mouse drawn to look like a rat.
Though this is probably due to the translation having a Completely Different Title, since the original French title was Asterix et les Indiens (Asterix and the Indians)
The Princess and the Frog: Considering the movie takes place in America, the eponymous "Princess" isn't an actual princess, she's just mistaken for one, but becomes one at the end of the movie, considering the "Frog" is of royal descent.
The two-parter Family Guy "Stewie Kills Lois/Lois Kills Stewie"; neither title is accurate. In part 1, Stewie appears to kill Lois, but she turns out to be Not Quite Dead. In part 2, Stewie does get killed, but it's Peter who kills him. And to top it all off, both episodes turn out to be a computer simulation.
And in the episode, Mac runs down several examples of foods that they have in Europe, including German chocolate cake.
Claymation is done using Plasticene® — clay would dry out and harden.
How the Grinch Stole Christmas! is actually about how he could steal the decorations and gifts associated with Christmas; he couldn't actually steal the holiday, and even then, he gives back what he stole in the first place.
Phineas: (After Candace and various others start falling from a plane) Wow, dumb luck. And over the Sea of Razor Sharp Rock Spires too! The Others: AAAAAAAAAAAAAAHHHHHHHH! Phineas: Good thing it was so inappropriately named! (Candace and the others land on ground made of pillows.)
Flounder from The Little Mermaid is not a flounder (a flat gray fish that disguises itself as the bottom of the sea floor), but some sort of yellow tropical fish with blue stripes.
Similarly, Marlin from Finding Nemo is actually a clownfish like his son, Nemo. This was lampshaded about halfway through the film when Nigel the pelican tells Gill that Nemo's father shares his name with that of "a popular sport fish." Also, Dory is not a dory, she's a blue tang.
The Quack Pack version of Duckburg, unlike the one seen in DuckTales and in the comics, is actually not populated by ducks (or any anthropomorphic animal), with the sole exceptions being Donald, Daisy, Professor von Drake, and the nephews, at all!
Also, Duckworth (Scrooge McDuck's butler), despite his name, is actually a dog.
The The Avengers: Earth's Mightiest Heroes episode "Iron Man is Born" does not retell the origin of Iron Man, nor does "The Man in the Ant Hill" show Hank Pym explore an ant hill. Some other episodes have the same names as comics they do not actually adapt, but most of them still sound relevant to the plot.
From Teen Titans the H.I.V.E. Five actually had six members in their third appearance, as Kid Flash quickly noticed.
In My Little Pony: Friendship Is Magic, there is a place known as the Crystal Empire. It's actually a city-state within the kingdom of Equestria, whose head of state is a princess (abeit one implicitly lower ranked than the reigning Equestrian diarchy), rather than an empress. Back when it was actually independent, it was ruled by kings and queens rather than an emperor or empress.
In the Disney film Tangled, Rapunzel's magic hair never gets tangled, in spite of the many things it is brushed over, tied to, etc.
Eight Crazy Nights hardly has anything to do with Hanukkah (outside of a few brief references) and may have very well just been a film set during the Winter season.
The Fantastic Four 1967 episode "The Menace of the Mole Man" adapts a comic titled, "The Return of the Mole Man!", while "The Return of the Mole Man" adapts a comic titled, "The Mad Menace of the Macabre Mole Man". The former episode's title doesn't match its comic because Hanna-Barbera had yet to adapt the first Fantastic Four issue. (When they finally did so, they left out Mole Man's scenes to boot.)
