I don't think arrested-adolescent humor will fade. Maybe the form will change, but I guarantee its replacement will still be based in immature behavior from mature figures.

In this quote, Adam McKay reflects on the persistence of arrested-adolescent humor, which is humor rooted in immature behavior exhibited by mature figures. He suggests that this form of comedy, which often involves childish or absurd behavior from adults, will not disappear. While the style or delivery of such humor may evolve over time, McKay believes that the essence of this type of humor—based on adults behaving in immature or silly ways—will continue to be a significant part of comedic culture.

McKay points out that, even as humor styles change, there will always be a space for this type of immaturity in comedy, particularly when it’s performed by mature figures. This reflects his belief that audiences will always find humor in seeing grown-ups act in ways that defy societal expectations of maturity. Whether through physical comedy, absurd scenarios, or off-the-wall antics, adults behaving like children will remain a core element of comedy.

The origin of the quote comes from McKay’s career as a director and screenwriter, known for films like Anchorman and Step Brothers, which feature this type of humor—grown men behaving in childishly ridiculous ways. His body of work often leans into this arrested-adolescent comedic style, showcasing how adults still engage in juvenile antics and absurd behavior, much to the audience's amusement.

Ultimately, McKay’s quote highlights the enduring appeal of immature humor within the context of adult figures. He acknowledges that while the specific form of this humor may change, the core idea of adults behaving immaturely will remain central to many comedic works. This reflects a broader theme in comedy where exaggerated, outlandish behavior often resonates because it highlights the absurdity of human nature and the ways in which we all, regardless of age, still carry elements of childishness.
