 In "Castle Greyhawk", TSR parodied its own scenario style, as a send-up of the illogical "gilded hole" labyrinth dungeons.The product contains many references to contemporary popular culture, along with a bitingly satirical treatment of TSR's approach to earlier "Greyhawk" publications.The module's back cover states "The common theme of this dungeon is that no joke is so old, no pun is so bad, and no schtick is so obvious that it can’t be used to confuse and trip up PCs!"
