Filthy Frank was the surreal comedy character created by George Miller for his YouTube channel, running from 2011 to 2017 before Miller retired the persona to make music as Joji. Short lines from his videos became staples of meme soundboards, passed around as reactions and punchlines long after the show ended. "I didn't see anything" is one of those denial moments, a guilty dodge that creators reach for whenever someone gets caught. It sits alongside fellow reaction staples such as BRUH, the kind of tiny clip that needs no setup to land.
