In 'Up The Chastity Belt' (1971) Lurkalot (Frankie Howerd) is a humble serf in Custard Castle, who runs a side-line selling chastity belts and love potions at the local market place. He's called upon to save the day when Sir Braggart De Bombast attempts to seize the castle and kidnap the beautiful Lobelia De Custard.
