Hanna Barbera was founded in 1957 by William Hanna and Joseph Barbera and became famous for cartoons including The Flintstones, Yogi Bear and Scooby-Doo. Across those shows the studio reused a distinctive library of exaggerated effects, so a single slam could serve for doors, crashes and falls in many different scenes. That repetition made the sounds familiar to generations of viewers. Online, editors treat this slam much like a punch sound, dropping it into meme edits, animations and game clips whenever a hard, unmistakably cartoon impact is needed.
