The Fools' Guild in Discworld is a satirical institution dedicated to training professional jesters and fools in the art of comedy, though their humor is often rigid, formulaic, and outdated. Located in Ankh-Morpork, the Guild teaches its members slapstick routines, bad puns, and custard pie-throwing, all within strict guidelines that regulate what is considered "acceptable" humor. Despite the intention of being entertainers, the Fools' Guild members tend to lack the cleverness and spontaneity traditionally associated with medieval jesters, who were known for their wit and ability to speak truth to power. The Guild is led by the "Lord of Misrule" and operates with a bureaucratic approach to comedy, making it a parody of both entertainment and rigid institutions.
