The clip comes from The Last Leg, the British television comedy show whose running jokes and soundboard buttons have long been shared beyond broadcast as short reaction audio. This button takes the familiar fairy-tale image of a knight in shining armour and replaces its hero with a blunt British insult, a piece of wordplay that fits the programme's irreverent, late-night humour. Once uploaded to soundboards, the two-second joke became easy to reuse whenever a clip needed a fast, rude deflation of someone acting grand, and that simple, repeatable punchline has kept it in circulation among meme editors.
