* ''Film/AbbottAndCostelloMeetFrankenstein'' ended with [[spoiler:the Invisible Man appearing.]]

* ''VideoGame/{{Warcraft}} 3'': In one of the Frozen Throne expansion missions, you can encounter a boss called "The Butcher", who guards an item called "Wirt's other leg". These are both references to Blizzard's {{VideoGame/Diablo}} franchise. The Butcher even plays the same sound clip as the Butcher from the original Diablo does when you encounter him. The item additionally has an extended tooltip, jokingly suggesting that the Diablo and Warcraft universes are connected.

* ''WesternAnimation/FindingNemo'': We see [[WesternAnimation/MonstersInc Mike Wazowski]] swimming through the end credits.

* In ''[[https://archiveofourown.org/works/51609004/chapters/130449952 Worm short stories and snippets]]'' story "[[https://archiveofourown.org/works/51609004/chapters/131159026 One Absolute Cluster-Trigger]]", a series of events leads to several parahumans being outside the locker where Taylor triggers, leading her to gain ComboPlatterPowers from each of them (Lung's dragon form, Hookwolf's metal blades, Shadow Stalker's shadow drop, Glory Girl's fear aura, Stormtiger's aerokinesis, and Panacea's unused ability to poison others). At the end of the story, Piggot (who has just been informed of the whole situation by Armsmaster) notes that they'll need a cape name for her, and Renick says they already have one in mind: [[VideoGame/TheLegendOfSpyro Cynder]].[[note]][[DontExplainTheJoke The joke being]] that Taylor's power-set matches up with Cynder's exactly]].]]

If the two works are owned by the same company, it doubles as CompanyCrossReferences. If owned by different companies, it can be a LawyerFriendlyCameo.

** Another strip had Garfield stuck clinging to a tree branch. Just as he says [[TemptingFate that things can't possibly get any worse]], he ends up tangled in a kite as an off-panel voice cries out, "[[CatchPhrase Good grief]]!"

* 1997 was the year of the Great April Fools' Day Comics Switcheroonie, in which a number of comic strip writers and artists handled each other's strips as a massive practical joke. In several cases characters from different strips met, such as Garfield and Jon having their house painted and leaving to visit [[ComicStrip/{{Blondie}} the Bumsteads]].

** Earlier, the main character notices a glowing barn making strange noises, and finds [[spoiler: [[Film/BackToTheFuture Doc Brown]] fixing the Delorean.]]

* Wrestling/BlackRose cheering on her former WWC client Bronco #1, "as a fan" while she was contracted to WWC's main rival IWA Puerto Rico, or perhaps Wrestling/AustinAries continuing to show up in Wrestling/RingOfHonor, "as a fan", while contracted to Wrestling/{{TNA}}. This was tolerated by IWA, [[ContinuityNod because Black Rose was originally a WWC audience member]] that Rico Suave had dared to get into the ring before he made her Bronco #1's valet. Austin Aries on the other hand was trying to get TNA's office to pay more attention to him and signed a new ROH contract on the spot when he got fired over the phone.

* The trope image is the LogoJoke for ''WesternAnimation/MortalKombatLegendsScorpionsRevenge'': instead of Westernanimation/PorkyPig pulling Westernanimation/DaffyDuck inside the Creator/WarnerBros shield, it's [[Franchise/MortalKombat Scorpion]] himself, complete with his catchphrase 'GET OVER HERE!'
** An even bigger example is the LogoJoke for the sequel ''WesternAnimation/MortalKombatLegendsBattleOfTheRealms'', wherein Scorpion is jumping around the logo instead of Daffy, and instead of Porky, Daffy, or another ''Mortal Kombat'' character pulling him back into the WB shield, it's none other than ''[[Franchise/ScoobyDoo Shaggy Rogers]]'', [[AscendedMeme a powerful aura surrounding him and eyes glowing]], who pulls Scorpion into the logo.

* ''Animation/HappyHeroes'': In Season 6 episode 14, a monster, contacting Big M. from far away, mentions being hit by Happy S. so hard that "I have no idea what cartoon I've ended up in!" In the background, Wolf Castle from Huang Weiming's other show, ''Animation/PleasantGoatAndBigBigWolf'' can be seen.

* The ripping parody channels Music/SiIvaGunner, Music/TimmyTurnersGrandDad, and Music/VvvvvaVvvvvvr occasionally use each others' RunningGags as a joke in a rip. A three-way crossover happened on 19 May 2023, when [=SiIva=] (who was mass-uploading [[VideoGame/TheLegendOfZeldaLinksAwakening Raft Ride]] rips), TTGD (doing the same for [[VideoGame/{{Omori}} 100 Sunny]]) and [=VvvvvaVvvvvvr=] (doing the same for [[VideoGame/Yume2kki Fairy Tale Path]] uploaded rips mixing their joke with both other channels'.

* In episode 8 of ''WebAnimation/InanimateInsanity II'', once the contests reach Meeple headquarters they hear a voice of the company's CEO. When they try to see who the voice belongs to, we see Gamey, the host of ''WebAnimation/Object Overload'' (Another popular {{Object Show|s}}), who points them towards Steve Cobs.

* The October 31, 2010 strip for ''ComicStrip/{{BC}}'' has The Fat Broad running a pumpkin pie stand. The Cute Chick asks her where she found enough pumpkins to make the pies. The Fat Broad says that she just found one really big pumpkin. Cut to [[ComicStrip/{{Peanuts}} Linus, Sally, and Charlie Brown]] in a pumpkin patch with Charlie Brown saying "I don't think he's coming, dude."

* In ''WesternAnimation/TheLionKing1994'', Zazu comments that Scar would make "a very handsome throw rug." In ''WesternAnimation/{{Hercules}}'', Hercules turns the Nemean Lion, who looks extremely similar to Scar, into a pelt (which he later tosses on the floor in frustration).

* ''VideoGame/{{Skate}} 2'' has an extremely rare voice line spoken by two police officers discussing arresting a man for a DUI and how his ID says he's from Tri-City Bay, the fictional city in ''VideoGame/NeedForSpeed Undercover''[[/folder]]

* The Adam West Batman show often featured a scene where Batman and Robin were climbing up a building with a guest star coming out of the window. On three occasions, a fictional character came out instead. They were Lurch from ''Franchise/TheAddamsFamily'', Colonel Klink from ''Series/HogansHeroes'' and ''Radio/TheGreenHornet''. ''Series/TheGreenHornet'' was the only one who was later featured in an entire episode.

* ''WesternAnimation/{{Hercules}}'' reveals that Zazu's suggestion that Scar would make "a very handsome throw rug" seems to have been proven true, as Hercules's headdress (which he later tosses on the floor in frustration) is Scar's pelt.
