I hope there's somebody out there who would find the phrase "Conan The Baratarian" funny. It conflates Conan the Barbarian with Gilbert and Sullivan's operetta, The Gondoliers, or The King of Barataria. I always assumed that Gilbert made up the word "Barataria," but that word has a history: the pirate and privateer Jean Lafitte, nearly a hundred years earlier, named his Mississippi stronghold Barataria.
Anyway "Conan The Baratarian" is not the most obscurely imaginable attempt at humor . I once made up a joke that only a bridge-playing bassoonist could laugh at.
