Maid Marian and Her Merry Men (1989)

Season 4: Episode 3

When the villagers catch colds the sheriff takes them to the seaside but, once there, forces them to build him and the king a holiday camp in time to celebrate High Forks Night. This commemorates a failed attempt to kill the Royal family which caused forks to go flying up in the air. The merry men are holidaying nearby and so Marian dresses as the food inspector, allowing her and her gang to infiltrate the camp, where they tell the villagers to feign having the Multi-Coloured Pimple Plague in order to escape.
