* [[http://www.youtube.com/watch?v=jh8b4qh-jW0 This early skit]] where Kermit speaks about the letter B. Then Cookie Monster (unnamed at the time) emerges and starts consuming the letter piece by piece. The B turns into an R, then a P, to an F, to a I? A small L? Number 1?, so Kermit tries to keep up with the letter change.
** Even though Kermit can't at the moment think of any words for the letter "P", in reference to the letter "F" is: [[GettingCrapPastTheRadar "Now the letter 'F' starts a number of words I can think of."]]
** Also in [[http://www.youtube.com/watch?v=QloUMRs5ryI the longer version of this sketch]] is Kermit's humorous rant about the future Cookie Monster's manners which prompts the monster to come back and apologize... with a big, slobbering, monster kiss on Kermit's face followed by Kermit's patent "Yeesh" face.
* Cookie Monster [[http://www.youtube.com/watch?v=C-PkQRh3QXA audition video for Saturday Night Live.]]
* At Luis and Maria's wedding, Big Bird cheers loudly, and Gina snaps his beak shut with both hands.
* [[http://www.youtube.com/watch?v=EAqGGpj0Ans Kermit showing what "mad" is to Cookie Monster as Cookie demonstrates "sad".]] Who would've thought Kermit was capable of losing his temper?
** Psst. [[http://www.toughpigs.com/a-frazzled-frog-is-a-funny-frog/ The Tough Pigs site's list of a number of times Kermit lost his temper.]] Includes a few ''Sesame Street'' skits, such as the one featuring Kermit's immortal line "This is a terrible place for a bus stop! What kind of bus is going to drive into my living room?!"
* In an early episode, the aftermath of Kermit's rectangle lecture visited by Cookie Monster. [[http://www.youtube.com/watch?v=vfzZGGe8Dho "It's a wreck, and a it's a tangle! Ahahahaha."]]
* A hilarious TakeThat at [[http://www.youtube.com/watch?v=WY8jr_qdQLs those who believe in the Veggie Monster rumors and the media in general.]]
* After Grover pesters Kermit too many times to purchase earmuffs, [[http://www.youtube.com/watch?v=Jb03Ig6SB3g Kermit confesses he doesn't have any ears.]]
* The skits that have dog-headed humans acting out various mundane activities:
** [[http://www.youtube.com/watch?v=Z-QiU1pPx-M Mechanic.]]
** [[http://www.youtube.com/watch?v=wgQNx_aRZgk Home Cooking]], made funnier with the [[ThrowItIn right cook's subpar discipline]].
** [[http://www.youtube.com/watch?v=94cYXJre8uk Barber.]]
* [[http://www.youtube.com/watch?v=OqZJyXSI7_g "Little Red Riding Cookie"]]. Particularly the fact that Cookie Monster views it as a melodrama masterpiece. Not to mention how hilarious the Grandma is.
* [[http://www.youtube.com/watch?v=RrJnzBFzEEY Don Music banging his head on the piano while songwriting with Kermit the Frog.]]
* Bert teaches his pigeon to play checkers. Ernie is suitably impressed, and says that a [[DancingBear pigeon that plays checkers has to be the smartest pigeon in the whole world.]]
-->'''Bert:''' She's really not that smart, Ernie. ''[...]'' Out of ten games we've played... she's only beaten me twice.
* [[http://www.youtube.com/watch?v=e_Uv6vD4v1A Bert is It!]]
* A crossover funny moment with ''Series/TheDailyShow'': After Jon Stewart pointed out that Grover's harried restaurant customer looked just like Republican Party Chairman Michael Steele, they were able to get that Muppet (or at least a replica) as their own Muppet Michael Steele, responsible for some of the show's best moments.
* The Sesame Muppets appearing on talk shows. They tend to get a little more PG-13 when there aren't kids watching.

*** "Me have crazy times in '70s and '80s."
*** "Me like the RobertDowneyJr of cookies!"
*** ''(Pointing to Stephen's Peabody Award)'' "Is that cookie?"
*** At the end of that show, the Award mysteriously disappears as Cookie Monster wipes his lips...
** [[http://www.youtube.com/watch?v=CXHCeRB21vY David Rudman performing Cookie Monster on-stage at Ragtag Cinema]] (one of the few Muppet performances where you can actually see the performer), talking about the media rumor that he's now the Veggie Monster. It evolves into a hilarious monologue in which he first claims "It TRUUUUUE! Yeah! No longer am me going to eat...delicious... crunchy... chocolatey... COOOOKIIIIES!", and then claims to have beat the addiction with a "cookie patch," and briefly renames himself "Brussel Sprout Monster," only to discover he doesn't like brussel sprouts. Finally, he gives up, claims that he'll remain Cookie Monster, even though he will continue to eat other things too: "Me eat, you know... Truck! Bicycle! Fire hydrant! That food group, right?"
* The Count's song from the 1975 ''Bert and Ernie Sing-Along'' album: "One bat hanging in the steeple/One bat flies in through the door/That makes two bats in my belfry/Wonderful! [[KarmaHoudini But wait... there's more!]]/Two bats hanging in the steeple, etc." ...and then the rest goes on [[ExactlyWhatItSaysOnTheTin just as you'd expect]]. Until he gets thrown in the shower.
* "[[Advertising/TheManYourManCouldSmellLike I am on a horse...]] Moo! ... cow." Not to mention [[http://www.youtube.com/watch?v=zkd5dJIVjgM everything before it.]]
* In ''Christmas Eve on Sesame Street'' during a discussion of Santa Claus:
-->'''Kermit:''' Who knows more about Santa Claus than anybody?
-->'''Patty:''' The elves!
-->'''Big Bird:''' Uh, Mrs. Claus?
-->'''Patty:''' ''[[MiracleOn34thStreet Macys!]]''
** [[http://www.youtube.com/watch?v=aOBL492A2oI Cookie Monster eating a typewriter.]]
** The ending with Big Bird (who spent the entire special worrying about how Santa would fit down the chimney) sputtering silently after Oscar asks him how the Easter Bunny is able to hide so many eggs in one night is priceless. Cue an [[FirstNameUltimatum "OSCAR!"]] from the humans.
* The entirety of the classic sketch "The Magic Apple" from ''Sesame Street''. Bob is narrating a book that is in turn being performed by Ernie and a couple of other muppets. Fourth-wall violations abound. But this sketch gets especially funny when they trot out a very reluctant Bert in drag, who had to play the part of the princess in the script because no one else was around to do so. "You look great, Bert. You're beautiful!"
* The entirety of [[http://www.youtube.com/watch?v=cUusX1Js6R0 Bert and Ernie Fish Call]]. Here Bert and Ernie go fishing is a classic example of ''Sesame Street'''s brilliant humor, especially when Ernie's rather unorthodox method of catching fish proves to be far more successful than Bert's more traditional approach.
** [[NoIndoorVoice "Heeeeree FISHY! FISHY! FISHY! FISHY!]] [[PunctuatedForEmphasis Heeeeeeeereeee FISHY! FISHY! FISHY! FISHY!"]]
** And then when Bert tries this method himself, he keeps trying to raise his voice louder and louder, until he successfully catches... a shark!
--->'''Shark:''' You called?
* Robert [=DeNiro=] teaches Elmo [[http://www.youtube.com/watch?v=zqHfser_9_s how to act]]. Hilarity and Surprises ensue. He even gives {{Shout Out}}s to some of his previous roles:
-->'''[=DeNiro=]:''' I can be a [[TaxiDriver New York City taxi driver]], [[RagingBull an out-of-shape boxer]], [[ArsonMurderAndJaywalking or a cabbage]].
* Forgetful Jones singing "Oklahoma" wrong (and Kermit's reaction each time).
* [[http://www.youtube.com/watch?v=jDwEzSoQp-Y Kermit's visit to the Wonderful World of T-Shirts]].
* Grover messing up with the pizza that Mr. Johnson ordered.
* [[http://www.youtube.com/watch?v=CTqCVJW2qOw ABC Cookie Monster]]: A little girl sings the alphabet song with Kermit, but every so often, giggling hysterically, she replaces one of the letters with "Cookie Monster". Kermit's reactions are priceless. After the fourth time, Kermit says, "Next time Cookie Monster can do this with you. I'm leaving! Hmmmph!" and storms off. It becomes a HeartwarmingMoment when the little girl immediately says, "I love you!" and Kermit comes back on: "I love you, too." And she kisses him.
* Oscar was, on the day of Gabi's birth, the only one making regular contact with Luis. Oscar, doubting his honor as a grouch, refuses to tell a soul whether the baby has been born. Bob uses reverse psychology to assure Oscar that he is as grouchy as ever. It doesn't work. Pretty soon, David and Gordon are about ready to kill Oscar. [[http://www.youtube.com/watch?v=DTGb3YVIt8o Take a look at this]]!
* [[http://www.youtube.com/watch?v=aR1DdMeVqTw Spider Monster.]]
* The forty third season premiere [[spoiler: features Alan hosting an important function for a cookie lovers' club. He tells Chris to take Cookie far away from Sesame Street, "...maybe Canada..."]]
* [[http://www.youtube.com/watch?v=Te70C_4getQ Normally the martians are seen as]] NightmareFuel, and they are for Ernie, but...
--> '''Ernie:''' Bert! BERT! The Martians are here, Bert! What'll we do, Bert?!
--> '''Bert:''' ''(completely deadpan)'' Ask them if they want any oatmeal.
** And then the Martians wiggle off to the kitchen to get some oatmeal.
* The whole [[http://www.youtube.com/watch?v=ksL_7WrhWOc "Waiting for Elmo"]] skit, parodying, of all things, ''Theatre/WaitingForGodot''. Especially when [[spoiler:the tree itself has enough of it and just leaves the set]].
* [[http://www.youtube.com/watch?v=shbgRyColvE Kermit, Cookie Monster and the Mystery Box]]. It's performed expertly and it is gut-bustingly hilarious seeing Kermit lose his temper, and CM performing WildMassGuessing.
** The first few seconds has this gem:
--> '''Cookie Monster:''' Is it cookie?
--> '''Kermit:''' Uh, no, it is not a cookie.
--> '''Cookie Monster:''' [[ScrewThisImOuttaHere Buh-bye]].
* One episode from Season 37 has Cookie Monster doing his own version of "Elmo's World" called (naturally) "Cookie World". It's an InternalHomage that goes close to SelfParody at some points.
* "[[RunningGag Eighty-five bats hanging in the steeple]]..." Back in the shower, Count!
* Kermit resolving a conflict between [[http://www.youtube.com/watch?v=KdIEm4AIWV0 Cookie Monster and Herry Monster over a bicycle]].
* [[http://www.youtube.com/watch?v=t7IHPJ0k9Bg Ernie has trouble sleeping]], so he tries CountingSheep, which is visualized to the audience. However, their bleating is so boring that Ernie then moves onto counting fire trucks, which Bert considers too loud, and finally balloons. Ernie imagines blowing up a balloon, which gets so big that it explodes loudly, shaking Bert out of bed, [[ScreamsLikeALittleGirl screaming like a girl]].
--> '''Ernie:''' Um... one?
** It comes back to haunt Ernie. In another [[http://www.youtube.com/watch?v=LH62UQ8pSR4 sketch]], the Count sleeps over at Ernie and Bert's place, but he isn't sleepy yet, so [[OhCrap Ernie suggests counting sheep]].
* [[http://www.youtube.com/watch?v=Zv04EDe4Dsg In another nighttime sketch]], Ernie left the faucet on after washing his hands before going to bed, which results in a DrippingDisturbance that keeps Bert awake. So Bert sends Ernie to turn it off. But instead of turning off the faucet, Ernie turns on a radio that plays loud music to drown out the dripping (the music heard is quite hilarious in and of itself). Then, instead of turning off the radio, Ernie turns on an even louder vacuum cleaner to drown out the radio. Finally, a frustrated Bert shuts off the racket and then finally settles down into bed for peace and quiet. Alas, Ernie snores as he sleeps!
--> '''Bert:''' ''(sadly)'' It's not fair.
* In a [[http://www.youtube.com/watch?v=yYzbD5Hwvbk third nighttime sketch]], Ernie wants to know what time it is. But it's too dark to read the clock, so, unable or unwilling to wait until morning, he tries a new method: he leans his head out the window and sings loudly, "O SOLO MIO, O SOLO YOU-O!" This wakes up the whole neighborhood who all yell at him to stop singing because it's 3:00 AM. Satisfied that he knows the time now, Ernie goes back to bed. The whole time, Bert, of course, is not amused.
** While no one besides Bert and Ernie is shown on screen, it's implied his singing wakes up the usual human adult cast. Hearing these normally kind individuals yell at Ernie to shut up is hilarious in its own right.
* The Rhyming Game skit. [[http://www.youtube.com/watch?v=logwI5wVdlI "Hey there lamp...that's a nice shade!..."]].
* [[http://www.youtube.com/watch?v=-qTIGg3I5y8 "Share It Maybe"]], another Music/CarlyRaeJepsen parody.
* [[http://www.youtube.com/watch?v=wGMB7Rn8KGE Pre-School Musical]], a parody of ''Film/HighSchoolMusical'', ends with the cast belting out the word "musical" with an [[IncrediblyLongNote Incredibly Long Riff]] while the announcer shills [[CashCowFranchise two sequels, an ice show, a Broadway adaptation, and an amateur production]].
** ''[[HamToHamCombat Melodic arguing]]''. John Tartaglia clearly had a great time.
* The first appearance of the Martians, where they [[http://www.youtube.com/watch?v=KTc3PsW5ghQ attempt to communicate with a telephone]]. Literally with the telephone.
* In one installment of "Abby's Flying Fairy School", Mrs. Sparklenose delivers this ItMakesSenseInContext line with the calm inflection that only a SeenItAll preschool teacher can muster:
--> Settle down now; this isn't the first time a chicken has gone hurtling through the roof of this classroom and I'm sure it won't be the last.
* Cookie Monster listening to a [[http://www.youtube.com/watch?v=3RfI-14UV-M game pitch.]] [[Creator/DoubleFine Tim Schaefer]] pitches a project about zombies, boring Cookie Monster to death.
* [[http://www.youtube.com/watch?v=_7jpz_55EdM Jack Black defines Octagon]] is both this, and MemeticMutation. Here, JackBlack tries to define the word "Octagon" to the viewers. However, he forgets to bring one. Cue Elmo with a stop sign. But [[TooDumbToLive Jack is completely unaware of the octagon right in front of him]].
--> '''Jack''': If I stop, how can I find an Octagon? How Elmo, HOW?!
* [[RuleofThree SIX HUNDRED AND FOUR BATS HANGING IN THE STEEPLLLLLLLLLLLLLLLLLEEEEEEEEEE!!!!!!!!!!]]
* While the 1991 version of [[http://www.youtube.com/watch?v=PM6ya7wTb58 Monster in the Mirror]] didn't add much besides making the song a CelebrityEdition, it adds this hilarious bit at the end, courtesy of TheSimpsons.
--> '''Bart''': Hey, wubba man!
--> '''Homer''': [[RunningGag BART]]!
--> '''Bart''': AH!
* The Crumby Pictures shorts, in which Cookie Monster parodies movies, such as ''[[http://www.youtube.com/watch?v=Yz9u-oG3BgM James Bond]]'', ''[[http://www.youtube.com/watch?v=b1__qqnfue0 Pirates of the Caribbean]]'', ''[[http://www.youtube.com/watch?v=G6FDts-erVw The Karate Kid]]'', and ''[[http://www.youtube.com/watch?v=eT7nD02Im5E Catching Fire]]''.
** ''Catching Fur'' has Cookie (as Cookiness) exclaiming, "Being strong heroine of entire franchise hard work!" and Peeta as... an actual pita.
** ''The Spy Who Loved Cookies'' spoofs the title songs of ''Film/{{Goldfinger}}'' and ''Film/{{Skyfall}}'', with the singer of the former evoking Music/ShirleyBassey pretty well.
* Grover and Madeline Kahn performing "[[https://www.youtube.com/watch?v=hsCOTsE4atQ Sing After Me]]" in which Kahn twice vocalizes the "Fiddle-diddle-dee" line. When she starts to do it a third time, Grover turns to her as if to say "Don't you dare!" Kahn proceeds to vocalize the line anyway after Grover sings his part.
