Old Gregg was played by Noel Fielding in the BBC comedy series The Mighty Boosh, first appearing in the 2005 episode The Legend of Old Gregg. The green-faced hermit lives under Black Lake and confronts Howard Moon while he is fishing, asking what he is doing in his waters. Clips and quotes spread widely on YouTube and forums in the late 2000s, turning the strange encounter into a lasting cult reference that fans still quote, remix and use as a possessive reaction sound.
