Charleyyy and Friends began as a show within a show in SuperMarioLogan, the long running YouTube puppet series created by Logan Thirtyacre. It is presented as the favourite programme of Bowser, who would rather watch Charleyyy's antics than pay attention to his family, and the short title jingle became an easy identifier for the gag. Clips and references spread through SML fan communities, edits and soundboards, where the recognisable call now signals an in joke for viewers who grew up with the series and its recurring characters.
