Hanna-Barbera built one of the most recognisable cartoon sound libraries in television animation, reusing short comic effects across many of its shows so audiences learned to associate certain squeaks, boings and skids with slapstick action. The skid effect became shorthand for a character running too fast and stopping too late, a gag that needed no dialogue. As classic cartoons were clipped and shared online, the sound moved onto soundboards and into short-form video, where editors still use it because it is instantly understood and instantly funny.
