arthur
Explanation
This comic imagines what would happen if King Arthur returned in Britain's hour of need, as the Arthurian legend promises. The joke is that Arthur, a medieval warrior king, is hilariously unsuited for the modern world. When he arrives, he is "clearly delusional" to bystanders, who see a man in costume ranting about being king. The humor escalates as Arthur reacts to modern national concerns -- invoking national security and drawing a sword -- only for bystanders to respond with bureaucratic modern reactions like calling the authorities.
The comedy draws on the classic fish-out-of-water premise: the legendary "once and future king" returning to a Britain that has no use for a sword-wielding monarch. It satirizes both the romantic notion of a mythic savior returning and the mundane reality of modern civic life, where someone claiming to be King Arthur would simply be treated as a public nuisance. The punchline lands on the gap between epic legend and banal reality.
