- Terrence of KateModern is an unusual case. When he reinvents himself as bespectacled, cardigan-sporting religious nerd Terry, he is recognised almost immediately by the other characters. However, it somehow doesn't occur to them that quiet, harmless Terry might be the murderer. He later plays this trope straight as the straight-jacketed Patient # 12.
- In Englishman, Englishman's Battle Butler (known only as Butler) also moonlights as a supervillain named The Butler. A deconstructed example in that it appears to play this trope straight (E'man never connects the two) but Butler never actually bothers with a disguise, rendering it PoMo.
- Ashens And The Quest For The Gamechild parodies this. After fighting and tying up some guards, Stuart references the scene in which Luke Skywalker infiltrated the Death Star by wearing Stormtrooper armor, and then remarks they they could do "the exact same thing", with the camera panning onto the guards. Queue Stuart and Geoff attempting to bypass security by literally wearing Stormtrooper armor.
- One CollegeHumor video that is a Take That! to British Petroleum's response to the 2010 Gulf oil spill. Tony Hayward and other executives in BP's London offices announce to us after showing a video from an actual focus group that cleaning up the spill is difficult, so they're changing their name to Baby Otter Smiles & Co. Then Hayward and another employee Sally Harris (both of whom are wearing false mustaches) go to the house of Sarah Schneider (one of the focus group members). Sarah sees through their cover, says "You guys are monsters," and shuts the door on them.
- In Dr. Horrible's Sing-Along Blog, the titular character is not recognized by Penny, even though neither his "costume" or his "normal" clothes covers his face (he wears goggles, but only on his forehead until the last scene).
Hammer: You seem ... horribly familiar.
- Possibly justified in that Penny may or may not have heard of Dr. Horrible: she never mentions him; he's not a big time supervillain (yet), and the first time she sees him, she is under a lot of stress, but still ends up recognizing him.
- Most people miss Billy in the back of the soup kitchen as he glowers at Captain Hammer and pours the soup back into the pot instead of into the bowl. The irony of it is his idea of disguise is wearing a fake mustache and an apron and not wearing his hoodie.
- Paper-Thin Disguise is also subverted, as when Captain Hammer meets Billy, he instantly recognises him as Dr Horrible.
- Lampshaded in the Atop the Fourth Wall/The Spoony Experiment crossovers, where Linkara is always clueless as to who Dr. Insano really is, even when holding a picture of Spoony up to compare between.Linkara: Oh wait! I know this one! You're That Chick With The Goggles!
Dr. Insano: But- but- I'm not freaking black!
Linkara: But you are a woman, eh?
- Subverted in Kickassia, when several people recognize Spoony as "that doctor guy", despite his frantic efforts to pretend he's not Insano.
- Another Kickassia example. During the invasion the President of Molossia Kevin Baugh disguises himself as Baron Fritz von Baugh, Minister of Making Things Orderly. Although it is obviously him in disguise The Nostalgia Critic decides to go along with it and lets him stay. As it turned out doing this was a huge mistake on the Critic's part as it allowed Baugh the chance to plant a Apple of Discord within his already grumbling troops further sabotaging the future of Kickassia.
- Sapphire Episode III: How in the world could Ãlodie not tell that was Nikolai behind that eye-mask!?
- Dorm Life: "Josh? ...no, it's just a lamp."
- The Internet meme "seems legit" often involves this trope. Sure, that abandoned warehouse◊ is totally Willy Wonka's Chocolate Factory.
- In The Time... Guys episode with Timmy's Spanish teacher, Señor Tigre instantly realises that Dr. Chronos is not Timmy's father when Doc takes his multiple neckties off.
- This is used for fun when Lindsey Stirling dresses up as her own #1 fan Phelba — the only disguise is that Phelba has thick black glasses. A few people realize that Phelba and Lindsey look rather too similar, but since not enough people know them it generally works.
- The Thrilling Adventure Hour:
- On certain "Sparks Nevada, Marshal on Mars" segments we encounter Jib Janeen, an alien shapeshifter. Although Jib Janeen is always voiced by Paul F. Tompkins and speaks in the same goofy, high pitched tone regardless of who he's impersonating, the other characters are always completely fooled by the impersonation.
- "Desdemona Hughes, Diva Detective" features former actress Desdemona Hughes adopting various disguises to solve murders. The disguises are apparently legitimately good and, unlike Jib Janeen, Desdemona alters her voice to suit her impersonations. She also makes a very conspicuous show of leaving right before assuming a new disguise and the disguise is often of someone or something completely random and unrelated to the current situation. Nobody is ever suspicious for long and are always surprised at the actual reveal.
- In We Are All Pokémon Trainers, Lenore (Fool's Hydreigon) and Ammy (Umbra's Volcarona) use these to get their own Trainer's Licenses - they wore fake moustaches and trenchcoats. Lenore's case is more notable, because while Ammy was wearing a Pokémon-to-Human armband, Lenore wore the disguise as a Hydreigon.
- The Slender Man Mythos: The Slender Man is obviously not human, but it usually works. To the point where he can pull off the usual Child Eater shtick in broad daylight, in direct view of their parents, who usually refuse to believe he exists.
- Barney the Purple Dinosaur manages to escape from the Clugmuffer's hands by disguising himself as Boxman.
- In one episode of the The John Dredge Nothing To Do With Anything Show, regular character Derek Dalek tries passing himself off as Derek Dolak - but not very successfully, because even John grows suspicious:John: I must say, you rather remind me of someone.
Derek: Well, I am well known locally.
John: Your telescopic manipulator arm in particular looks familiar.
Derek: What? This little thing? (boing)
Derek: It's just there for show, John! JUST! THERE!! FOR!! SHOW!!! [exterminates a tree]
- Scary News out of Tokyo-3: Anyone with any knowledge of Neon Genesis Evangelion should be able to guess immediately who's hiding behind the transparent handle of "ZeroGirl00" — she's one of several characters with inside knowledge of NERV, and she has a tendency to talk about the Pilots in I Have This Friend... fashion. Unfortunately, none of the other characters are in a position to figure out the truth until she finally comes out and admits it.
- From El Chigüire Bipolar: Maduro [who is already moustachioed] goes out wearing a fake moustache hoping that nobody recognizes him.
- Dice Funk: Rinaldo concocts an entire alter ego, only for it to immediately fall apart under the slightest bit of scrutiny.Leon: I'm Filet Mignon from Pottsylvania!
- An Outside Xbox video discussing the use of this trope in video games is presented by "a person you've never seen before", who is very obviously one of the channel's usual presenters hidden behind a wig, a false nose, and a Line-of-Sight Name. Played with at the end of the video when it turns out he isn't the actual presenter, who shows up and chases him away.
- FreedomToons: After Dave Rubin's guests vow never to come back because he's too agreeable, he instead decides to interview Rave Dubin, a webshow host who is very... agreeable. And wears glasses.
- Sailor Moon Abridged pokes fun at the fact that the title character never wears a mask but is never recognized in her superhero form. For example, in one episode, when Tuxedo Mask (actually Nephirite) sends letters to find Sailor Moon and the title character gets one, Luna questions how he found her and offers an idea.Luna: It's probably because your hair is pretty...unique and you don't wear a mask.
