Old Gregg first appeared in The Mighty Boosh, the British surreal comedy created by Julian Barratt and Noel Fielding, with Fielding playing the lonely, love-struck sea creature who lives in a cave beneath Black Lake. Fans began sharing short audio clips of his most quotable lines as the show gained a cult following online, and the character's odd mix of menace and romance made him a lasting favourite for reaction edits. The 'Don't lie' moment survives because it is instantly recognisable even out of context, giving creators a quick way to call out dishonesty with humour rather than anger.
