Old Gregg is a merman character from The Mighty Boosh, the British surreal comedy created by Julian Barratt and Noel Fielding. He appears as a flamboyant creature living in a cave beneath a lake, obsessed with Howard Moon and famous for his strange songs and catchphrases. The self-introduction became one of his most quoted moments, circulating first through television clips and later through YouTube edits, soundboards and meme pages. Its staying power comes from how instantly recognisable the voice and delivery are, even in a clip lasting barely a second.
