The 'Do You Ever Look at Someone and Wonder, What Is Going On Inside Their Head?' meme originates from the 2015 Disney-Pixar film Inside Out. The line is delivered by Joy during the film's opening sequence to introduce the concept of emotions controlling a person's actions. On the internet, the template is used to poke fun at people (or animals) exhibiting bizarre, vacant, or hyper-fixated behavior. By pairing the quote with a second image—often showing a chaotic dance, a specific song on loop, or a nonsensical video—creators illustrate the hilarious disconnect between a person's calm exterior and their wild internal monologue.
