SMG4 is a long-running Australian YouTube series created by Luke Lerdwichagul that began in 2011 as Super Mario 64 machinima before growing into original animated comedy. Built around Mario and other Nintendo characters in absurd, fast-paced stories, it became a major source of internet memes, reaction clips and short audio snippets shared across YouTube, TikTok and Discord. Fans still reuse its sounds because the humour is instantly recognisable, even in a clip lasting only a couple of seconds.
