Would you consider the Hitchhikers Guide to the Galaxy series absurdist humour?
NO, not according to the definition in the first source below I would consider th “Hitchhikers Guide” to be a classic parody along with other great parodies such as “Candide” by Voltaire or “Catch-22” by Joseph Heller. A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.
