After Darwin returned to England from a journey to the Galapagos Islands with his new pet (and love of his life) he had to think quickly of a way to rationalize his new relationship to the snooty peoples and the queen. It all began to make sense to him when he began to ponder the origin of species. The book he created, which is viewed today of paramount importance to society, was originally written on the back of a copy of the 18th century British porn magazine 'Tankards'. Darwin had his new chimpanzee girlfriend transcribe it while they both were in a drunken stupor, she really did not understand what she was doing, and only agreed to write for him because tankards turned her on as well.
