* ''WebAnimation/BarbieLifeInTheDreamhouse'': While Teresa had her {{Ditz}}y moments from the start, they were generally more subtle and mostly consisted of silly lines, while in later episodes her ditziness gets much wackier, such as eating all the cupcakes she and Barbie made for a contest and spending an episode thinking she's a unicorn.

* Caboose from ''Machinima/RedVsBlue''. This was explained in-universe as the result of the trauma of losing his girlfriend ([[CargoShip Sheila the tank]]) having his mind controlled by [[AIIsACrapshoot O'Malley]] and not being too bright to start with.

* While LetsPlay/LewisBrindley hasn't exactly gotten ''stupider'' per say, he has become considerably wackier than he used to be. For context, in the very early days of the LetsPlay/{{Yogscast}} it was simply Lewis and [[LetsPlay/SimonLane Simon]], with Lewis as the StraightMan and Simon as the wacky {{Cloudcuckoolander}}. Since then, the Yogscast has expanded ''significantly'', with many more members of varying degrees of intelligence/sanity, meaning that Lewis' more silly moments became considerably easier to notice.

** Happened to both WebVideo/TheNostalgiaCritic and WebVideo/TheNostalgiaChick. The Critic used to be of average intelligence before morphing into a ditz with almost no common sense but can very insightful when he wants, and the Chick used to be an InsufferableGenius before becoming a KnowNothingKnowItAll who is oblivious to most things going on around her. TropesAreNotBad of course, their characters seen as much funnier now.

* The reviewers of Website/ThatGuyWithTheGlasses, whose characters are often not the smartest or most stable people anyhow, all seem to take stupid pills for the annual MassiveMultiplayerCrossover anniversary films and forget about the intelligence, resources or super-powers they've displayed in their own series. This is more or less justified by being a kind of RecursiveCanon, where the characters have made their videos instead of living them, but are still those characters instead of the people who actually play them.

* ''WebAnimation/HomestarRunner'': Homestar himself. Which makes his [[SmartBall random moments of intelligence]] all the more hilarious. He once recited Coulomb's Law when asked "What is 2 plus 2?" (when Strong Sad reiterates the question, Homestar naturally gets it wrong), and actually outsmarted Strong Bad by getting him to say something stupid.
