----
* ''Series/{{The 100}}'': Jasper and Monty filled this role in Season 1. When they got involved in a more intense and dramatic storyline for Season 2, Wick stepped up as the main funny guy (with a knack for making other characters more snarky whenever they're around him). Murphy also starts to fill this role late in Season 2, serving as the DeadpanSnarker towards Jaha's messianic zeal.
* ''Series/TwentyFour'': Chloe O'Brian is this, as far as a serious show like this allows anyone to be.
* ''Series/{{Alias}}'': Marshall.
* ''Series/{{Arrow}}'': Felicity Smoak went from one-off episode guest appearance to essentially the female lead thanks to her awkward quips and the actress's comic timing. (Though she also acts as TheSmartGuy). As the show started off rather sober in tone without a resident funny guy her handful of scenes significantly lightened the mood (she actually managing to get a ''smile'' out of [[{{ByronicHero}} Oliver]]) and she was brought on as a regular. [[spoiler: In an unusual case she's become Oliver's main LoveInterest while also remaining the PluckyComicRelief.]]
* ''Series/BabylonFive'': This was Vir's role early in the series, until CharacterDevelopment began kicking in during Season 2.
* ''Series/BandOfBrothers'':
** It's resident [[ManOfAThousandVoices master of parody]] George Luz. Considering the series is set in WWII, he has some elements of the SadClown.
** His friend Perconte also qualifies, and so does "Skip" Muck.
* ''Series/BoyMeetsWorld'': Eric started off as the ChickMagnet but when that role was taken over by Shawn he became this. And then things just got [[CloudCuckooLander weird...]]
* ''Series/BuffyTheVampireSlayer'':
** Xander and later Andrew. Though the writing is uniformly witty enough that all characters get their day in the Plucky Comic Relief sun.
** This is true with ''all'' Creator/JossWhedon shows, but there is still one or two characters in each series who do virtually nothing ''but'' be funny, in addition to fulfilling their role in the cast. In chronological order: Lorne on ''Series/{{Angel}}'', Wash on ''{{Series/Firefly}}'', and Topher on ''{{Series/Dollhouse}}''.
** ''Firefly'':
** Lampshaded:
--> '''Kaylee''' Did Zoe seem a little, er, funny to you at breakfast?
--> '''Wash''' C'mon Kaylee. We all know ''I'm'' the funny one.
** DeconstructedTrope with Lorne: the toll that being the Comic Relief takes on him by the fifth season is seriously rough.
** Harmony, however, remains her airheaded, self-absorbed self throughout.
* ''BreakingBad'' gives us Saul Goodman, who was created for this purpose after Vince Gilligan felt the show was getting too dark.
* ''Series/{{CSI}}'': Greg Sanders, the DNA specialist, was originally an excellent example of this trope. Later in the series he has several serious character arcs. He also becomes one of the most experienced [=CSIs=] on the team. His role has been taken over by Hodges and the supporting [[LabRat Lab Rats]].
* ''Series/DoctorWho'': Earned a LampshadeHanging in the episode ''The Unicorn And The Wasp'', when the Doctor calls Donna "The plucky young woman who helps me out":
-->'''Donna:''' 'The plucky young woman who helps me out'?
-->'''The Doctor:''' No policewomen in 1926.
-->'''Donna:''' I'll pluck you in a minute!
* ''{{Series/Emergency}}'': Chet Kelly. Station 51's resident [[ThePrankster practical joker]] and VitriolicBestBuds with Gage.
* ''TheFlyingNun'': Sister Sisto. In the pilot it was explained that she is studying English sayings in preparation for her eventually teaching in the United States. From that point on her running joke was to say something like "We need to get on the circle!" to immediately be corrected by one of the others "Uh, that's 'ball', Sister."
* ''Series/GameOfThrones'':
** Tyron Lannister can lighten up any scene, even the most violent ones (his [[spoiler: bludgeoning a man to death with his ''shield'' easily counts as one of his most badass and amusing scenes in the series.]]) He also bucks the trend in that he is [[HiddenDepths neither dim-witted]] nor [[MagnificentBastard genuinely concerned for anyone around him.]]
** Oh, he's plenty concerned for others. [[JerkWithAHeartOfGold He just doesn't show it often.]]
* Brittany S. Pierce from ''Series/{{Glee}}'' served as this for at least most of the first two seasons 2
* In ''Series/{{Glue}}'', the role is fulfilled by [[TheStoner Rob]] and [[TheDitz Annie]]. The latter is a straighter example since she has no character arc of her own.
* ''HarpersIsland'': In this murder mystery, Cal and Chloe provide much-needed wacky romance hijinx between all the deaths. They even have a short breather episode after the [[FamilyUnfriendlyDeath head spade incident]] when they try to retrieve Chloe's engagement ring. [[spoiler:When they both die in episode 11 of 13, it's a sign that there [[ShooOutTheClowns won't be any more funny bits thence onwards]].]]
* ''Series/{{Heroes}}'': Both Hiro and Ando.
* ''Series/{{JAG}}'': Bud Roberts on seasons 2,3 & 4.
* ''Series/{{Lost}}'': Hurley's role began this way, but has become less so as the character has become more important.
* ''Series/{{Mash}}'': Klinger so seldom got into the dramatic plots of the episodes that his SarcasmFailure was more effective than Hawkeye's ("Mail Call Three", "Period of Adjustment", "Death Takes a Holiday").
** In latter seasons, occasional character Sergeant Rizzo took on this role--his main job being to goof off, sleep, and tell quirky stories about his home in Louisiana.
* ''Series/{{Monk}}'': Randy Disher. His quirky antics and wild theories really give a nice dose of humor in the show. Still he is semi-competent and is always in the right place when he's needed.
* ''Series/MrLucky'': Andamo plays this role. Even when being held hostage by a murderer with an itchy trigger finger, he keeps trying to make light of the situation.
* ''Series/TheOC'': Taylor Townsend. As the series [[WackyGuy Wacky Girl]] she was a welcome relief from the sometimes overpowering angst of the penultimate season. Usually her wackiness was paired with Seth and Summer's in the aforementioned season to provide comic drama, if such a thing exists.
* ''Franchise/PowerRangers'' has had a share of these characters throughout its many seasons.
** The best known examples are off course Bulk and Skull from the original ''Series/MightyMorphinPowerRangers''. A FatAndSkinny duo of {{Butt Monkey}}s who constantly try out schemes for their own gain, only for said schemes to backfire. Usually this results in slapstick humor. The duo was apparently so popular, that a stand alone series was planned for them in which they ran a hotel. This was the reason why the characters got turned into chimpanzees for the first half of PowerRangersTurbo. But ultimately, the higher ups decided such a series would not work, causing the actors to return to Power Rangers.
** Joel Rawlings of ''Series/PowerRangersLightspeedRescue'' is this. Most of the humor of this series derives from his failed attempts to get dates with a female scientist or trying to skip training.
** ''Series/PowerRangersNinjaStorm'': While the villains in this season are pretty lighthearted and comedic to begin with, villainesses Marah and Kapri fit this trope, as their main purpose seems to be playing the role of spoiled brats to their uncle [[BigBad Lothor]].
** ''Series/PowerRangersDinoThunder'' has Devon and Cassidy. They are frequently compared to Bulk and Skull, but play a much more subdued role compared to them. Cassidy and Devon start out as an AlphaBitch and her lackey, who, like Bulk and Skull, try out schemes for their own gain, only for them to backfire. But later on, they grow out of these stereotypes and this role and develop distinct personalities.
** ''Series/PowerRangersOperationOverdrive'' features Norg the Yeti. He is a dimwitted Yeti who lived in the cave one of the main villains decided to take as his base.
** ''Series/PowerRangersRPM'': Ziggy Grover, the green ranger, fits this trope pretty well. His only task in this team seems to be being the victim of as many accidents as possible.
* ''Series/PrettyLittleLiars: Definitely'' Hanna.
* ''Series/{{Psych}}'':
** Shawn Spencer has the distinction of being the main character AND the Plucky Comic Relief. DeconstructedTrope in "An Evening with Mr. Yang," when it's revealed that Shawn ''needs'' the Plucky Comic Relief in order to distance himself from the things he has to deal with. When Shawn's mother is kidnapped by the serial killer and Shawn suffers a HeroicBSOD, [[StraightMan Gus]] steps forward to take over the Plucky Comic Relief, [[OOCIsSeriousBusiness much to the confusion of everyone around them.]]
** Woody TheCoroner, a {{Cloudcuckoolander}} who is there to say and do funny, and [[RefugeInAudacity sometimes wildly inappropriate]], things. In the seventh season premiere ("Santabarbaratown 2"), Woody's the one who provides most of the comic relief because Shawn[[spoiler: 's father has just been shot]] and the situation is too serious for him to make jokes.
* ''PunkyBrewster'': Allen Anderson was the show's comic relief, although his failure to learn CPR in "Cherie Lifesaver" left him sobered because it nearly took Cherie's life (she was trapped in a disused refrigerator and was found unconscious. Punky and Margaux used CPR learned at school to save her.)
* ''Series/{{Revolution}}'': Aaron Pittman. He says some pretty funny things, like in "[[Recap/RevolutionS1E7TheChildrensCrusade The Children's Crusade]]", when he compares the group of kids they find to ''Children of the Corn'', and annoying little Ewoks from ''Star Wars''.
* ''Franchise/SuperSentai'': There are a few of these, including [[Series/DaiSentaiGoggleFive Goggle Yellow]], [[Series/TokumeiSentaiGoBusters Beet Buster]], and [[Series/ZyudenSentaiKyoryuger Kyoryu Black]].
* ''Series/WizardsOfWaverlyPlace'': Max, whose dialogue consists of nothing but bad one-liners.
* ''Series/XenaWarriorPrincess'': Joxer ([[MilesGloriosus the Mighty]]). No matter how hard or how often he tries to be TheLancer, the AntiHero, or the VillainProtagonist, poor man.
-->'''Joxer''': Now listen, I'm fierce, and I have a lust for blood. As a matter of fact, if a couple of days go by and I haven't shed some blood, I get ''very depressed.'' Blood and me go together like a horse and chariot! [[BloodBath I once bathed in a tub of blood]]! My nickname is Bloody Joxer!
-->'''Xena''': If you like blood so much? Keep talking.
* ''Series/TheXFiles'': The Lone Gunmen. [[spoiler: This did not save them from a random and contrived death in the last season, in an otherwise comedic episode.]]
