SuperMarioLogan, now known as SML, was a YouTube channel created by Logan Thirtyacre, known for its unique blend of comedy, animation, and often violent or mature themes. The channel was initially popular for series like "Mario and Luigi's Stupid and Dumb Adventures," but later became synonymous with the character Jeffy and the destruction of objects for comedic effect. Despite containing mature themes, a significant portion of the fanbase, particularly after Jeffy's introduction, was comprised of younger children, leading to a large cult following.
