Old Gregg is a surreal character from the British comedy series The Mighty Boosh, played by Noel Fielding, who lives in a cave beneath Black Lake and becomes obsessed with Howard Moon. His strange mannerisms, songs and love of Baileys made him a cult favourite long after the show, and short clips of his voice circulate widely as reaction sounds. This deal moment works because it distils that weird charm into a single agreement, making it easy to reuse whenever a creator wants an offbeat yes.
