If a character enjoys a TV show, book, movie, or toy marketed to a younger demographic which they've clearly outgrown, the audience may be scratching their heads in confusion. On the upside, works primarily intended for children tend to attract a demographic of adults or adolescents due to clever writing, unique animation, likable characters, Parental Bonuses, and other material they would have paid little attention to as a young child due to a short attention span and undeveloped mind. On the downside however, this could be an attempt to portray a character as immature or stupid, especially if the work is geared to toddlers and preschoolers. Their enjoyment of this series can be a sign that they're a Kiddie Kid/Manchild or Cloudcuckoolander. However, there are occasions where this is just used as a one-shot gag Played for Laughs and never brought up again. The work is usually a Show Within a Show parody of a Real Life work, especially in children's works where copyrighted names are less frequently appearing.
If the character is otherwise mature to the extent of an Only Sane Man, their low-key enjoyment of a children's work could be a Hidden Depth to show they're Not So Above It All.
For the inverse, when characters (mainly children) enjoy a work intended for older audiences, see Entertainment Above Their Age.
Sub-Trope of Periphery Demographic. Can be deconstructed and subverted by Animation Age Ghetto, Subverted Kids' Show, What Do You Mean, It's Not for Kids?, or What Do You Mean, It's for Kids?. For real-life people who have goofy tastes, see One of Us.

- Clueless: Cher and Josh are shown watching The Ren & Stimpy Show on TV. Josh judges Cher, questioning why she still watches cartoons as a 16-year-old, but Cher reassures him by stating that Ren and Stimpy are "existential".

- The Big Bang Theory: The main guys, particularly Sheldon, get hit with this the most, due to the juxtaposition of their incredible intellects with their manchild tendencies and interests in superheroes, collecting action figures, cosplay, and such.

Lizzie takes a stand towards the end when she tells the entire school that Clover and Daisy, the two protagonists of The Magic Train, can teach them a lesson in loyalty and confidence, ending the episode with the entire school (sans Kate) joining in a musical cover of a dorky song from the show expressing pride in silliness.
