- The Trix Rabbit has tried about a million of these. Subverted in that they never work for more than a few seconds, and the few that do work are foiled by the Rabbit's undeniable addiction to the cereal. One good disguise the Trix Rabbit once used was to somehow turn himself into a cute, adorable bunny (they used a real rabbit in the commercial) and changed tactics, not talking at all and simply trying to sneak up on the kids. Unfortunately, his addiction to it gave him away as it always did. Another aversion that actually worked was the time the Trix rabbit used a full bodysuit in this infamous commercial.
- Barney Rubble in the Pebbles commercials, though Barney has had his share of ultra-realistic disguises involving rubber masks. This 1972 commercial was one of the first to show Barney pulling this stunt. In this case the ONLY change was putting a fake beard on. And he still managed to fool Fred.
- An ad for cheap cell phone service featured a woman who was saving money for her expensive cell plan by having her son travel free on a plane trip. She'd dressed him in a floppy-eared Halloween costume and stuffed him inside a pet carrier; hearing them converse, a baggage handler marvels at the "talking dog".
- Duke, the dog from the Bush's Baked Beans commercials once appeared in a labcoat and false mustache, posing as a food science researcher. For those who haven't seen these ads, be aware that the dog is a real golden retriever, not a cartoon mascot. He's also shown up as a Bedsheet Ghost of the recipe owner Jay Bush's grandfather, but is revealed when Jay explains, "Grandpa didn't have a tail."
- Seen in a TV ad for Speedway, featuring a contest for their Speedy Rewards card loyalty card. A man keeps coming in and using his card, wearing a series of ridiculous disguises. Finally, the clerk, who isn't fooled for a minute, tells the customer that he can use the same card as many times as he wants and still be entered in the contest each time. MST3K Mantra, since if you think about it for more than a few seconds, you realize that no matter how well he disguises himself, the card always carries the same computerized details about his identification. (Then again, he might not be smart enough to realize that.)
- A Dunkin' Donuts ad had Fred the Baker (who's a portly little guy with a moustache) spying at a rival donut place dressed as a woman, coyly holding a hand over his moustache and not fooling the anxious counter man.
- In one McDonald's commercial from the '70s, Ronald dresses up as a mailman to thwart an attempt by Grimace (who was evil at this time) to steal some milkshakes. The disguise is little more than a hat.
- One of the Naked Gun-type ads for Red Rock Cider has the Comedic Hero working undercover in an ice cream van called "Mr Policey" and labelled UNMARKED POLICE CAR. This naturally leads to a Visual Pun where a customer asks for a couple of cones and gets two traffic cones instead.Frank Drebin: A hot tip led Sgt. Doughray and me to Ascot. We mingled unobtrusively for a while before dividing forces. (Doughray and Drebin are wearing dark men's suits and fancy ladies' hats.)
- Subverted in a commercial bumper for Cartoon Network. A cop is chasing a thief down the street and the thief ducks in an alley. The cop follows him to find the thief dressed in drag, and tries to flirt with him. The cop isn't fooled for a second and promptly arrests him. A caption then appears saying "You are not Bugs Bunny."
- At the 2012 Spike Video Game Awards, newbie game developer Joakim Mogren and his studio, Moby Dick, surprised everyone by showing a trailer for what seemed to be a stealth/horror game called The Phantom Pain. By the end of the trailer, fans had deduced that Joakim was an anagram for Kojima and Mogren was a reference to his mysterious Project Ogre, identifying the main character from the trailer as Naked Snake. Finally, the negative space in The Phantom Pain's logo? It happens to perfectly fit the words Metal Gear Solid V. Despite all this being figured out immediately, Kojima kept the ruse up until the real game and the real developer, Kojima Productions, obviously, was finally announced at GDC 2013.
- In this FedEx commercial, two deer fool a couple of poachers with nothing but novelty shop "Goofy Glasses".
