George Miller is a Japanese-Australian YouTube personality, singer, songwriter and musician. He is best known for his absurdist YouTube channel, consisting of music, rants, ukulele performances a bizarre show, with all of the main characters played by him, and his varied musical compositions.

As a YouTuber, he portrays the titular character (and pseudonym) Filthy Frank on his channel. Additionally, Miller's video titled Do the Harlem Shake (Original), which originated as a clip on the video "Filthy Compilation #6 – Smell My Fingers", has been viewed 58.5 million times (as of October 2017). The original clip led to the creation of the Harlem Shake meme,which was directly responsible for the debut of the song "Harlem Shake" (by producer Baauer) atop the Billboard Hot 100. Additionally, he has two other channels: TooDamnFilthy (a secondary channel) and DizastaMusic (an early incarnation of TVFilthyFrank, although it is no longer used due to Miller's fear of it being forcibly deleted).

As a musician, he either records under Pink Guy, a persona featured prominently on his 'show', or under the stage name Joji.
