History Comicbook / GastonLagaffe

* CharacterizationMarchesOn: Bertrand Labévue is at first just another Gaston that flops around, hence the last name. Afterward he became TheEeyore.

* CordonBleughChef: Gaston's custom recipes are so weird, just hearing him describe them is enough to induce nausea. Strangely enough, some people are actually curious to taste his cooking (such as strawberry cod, whose main problem is apparently the cooking odors). One recipe starts with browning six onions in a liter of orange juice and goes downhill from there.

** When Gaston have to be taken to an hospital because he ate a miniature plane, one surgeon play with it while another one ask him to give it to him.

** A female secretary with long black hair who is Lebrac's love interest. Franquin said he once found a very fitting name for her, but forgot to note it down and then he couldn't remember it again. A supplementary illustrated article seems to confirm the secretary's name as "Solange", as the illustration makes her look like this recurring character, but it wasn't drawn or written by Franquin, so its canonicity is very dubious. That nameless secretary tends to be erroneously called "Sonia" which is actually the name of a different dark-haired lady secretary who stopped appearing in the comic before the nameless secretary appeared. The Delaf comic reboot seems to continue keeping her anonymous.

** Although Gaston's cat and seagull become his most recurring pets once they were introduced, they're never given names, unlike several of his others pets. The cat has been called "Chat Dingue" (Crazy Cat) in some material, but it's very doubtful that's its actual given name.

** In the early comics, there are a series of strips where the orange juice brand "Piedboeuf" becomes Gaston and Fantasio's trademark favorite drink to exaggerated levels. Fantasio can even convince the notoriously lazy Gaston to work just by promising him a single glass of orange juice.
** The later comics have a series of strips advertising the "Bidule" batteries. These strips use a running gag where Gaston would put said batteries in various electronics, only for things to [[GoneHorriblyRight go horribly right]] because the batteries make electronics ''too'' powerful. A notable example include a strip where Jeanne uses a flashlight on the beach at night, only to be confused by a lighthouse by an angry sailor. These strips always end with Gaston saying, "This is Bidule's fault. They make batteries too powerful."

* StickySituation: Gaston has once a DreamSequence where he uses an old WWII bomber against a whaler boat -- dropping a ''glue'' bomb of his invention on the crew, leaving them stuck together and unable to hunt any whale, to be freed at the end of the hunting season.

* AnimalStampede: Yes, Gaston can cause a stampede of wild animals right inside the Dupuis redaction, why do you ask? If you wonder, he is trying to dry up his collection of whistling decoys with a hair dryer...

* BeakAttack: Gaston's pet laughing gull is notorious for this, to the point that his coworkers have developed a duck and cover routine when they hear its distinctive screech. At one point it is seen using its beak as a can opener.

* CatchPhrase:
** De Mesmaeker's is ''"Les signerai jamais !"'' which means "I'll never sign them!" (i.e., the contracts).
** In ''[[AnthologyComic Le Journal De Spirou]]'', he also had ''"C'est la dernière fois que je présente une première page !"'' ("It's the last time I appear on the first page!") whenever said [[http://www.objectible.net/forum/showthread.php?39809-En-t%EAtes-de-Franquin/page2 first page]] depicts him in an uncomfortable situation.

** Gaston is a militant ecologist and pacifist, but his cars emits more exhaust than a truck race and he oftens assembles working military-themed models (tanks and bombers) to demonstrate what they can do in RealLife. Hilariously, he once put a giant balloon at the end of his exhaust pipe to catch all the gases, but afterwards he thought nothing of ''just emptying the balloon in the middle of a street!'' In result everybody in the general vicinity lost consciousness from carbon monoxide poisoning.

* IResembleThatRemark: A gag starts with a montage of panels where Gaston is scolded by various characters because of his usual immature behaviour. In the penultimate panel, Gaston complains he's fed up of being treated like a child. In the last panel, he's sulking in his office, which is filled with toys.

* {{Jerkass}}

** A new live-action film adaptation, simply titled ''Gaston Lagaffe'', was released in early 2018. [[HistoryRepeats It was also a failure]].

* NotInFrontOfTheParrot: In one storyline, Gaston brought a parrot to office. After just one day of hard work, bird had already learned to imitate loud snoring.
* NotMeThisTime:

** De Mesmaeker once trolled Fantasio with a latex imitation of himself; Fantasio didn't realise it so he spent the entire day trying to get the attention of the fake De Mesmaeker. De Mesmaeker is also sometime interested in Gaston's inventions and found his astronaut clock funny and made a contract with Gaston to mass product them. In another story, Gaston gives De Mesmaaker some soup he just cooked, and De Mesmaeker likes it so much he decides to get rid of the contracts he was supposed to sign... to make a contract with ''Gaston'' concerning the soup recipe!

* ShipperOnDeck: People in the redaction seem to ship Gaston and Jeanne. At one point, they even trick them into going under some mistletoe.

* SirSwearsALot: Fantasio and Prunelle. While Prunelle has his signature ''"Rogntudju!"', Fantasio's language is censored out by SymbolSwearing.

* SpellMyNameWithAnS: Is De Mesmaeker or Demesmaeker? Canonically, it's De Mesmaeker (Jidéhem -- Jean De Mesmaeker). But since the speech bubbles are always written in all caps, and by hand, the lettering can get a bit crowded.

* ThereAreNoTherapists: De Mesmaeker really, ''really'' needs to see a therapist, and ''fast'', considering how much any hindrance leads him to refuse to sign the contracts and literally turning red with anger. (He probably needs to see a heart surgeon soon enough, in any case.)

--->'''Prunelle:''' If you find [Gaston], you knock him up, [[BoundAndGagged you bind him, you gag him]] and you hide the body in a closet...\\

* HeroesWantRedheads: Mademoiselle Jeanne is a redhead.

** Subverted with Jef. He is unnamed in the comics, but his identity is confirmed on the official website.
