There are many children's books retelling the stories of the operas, or stories about the history of the famous partnership, including two by Gilbert himself. There are also children's biographies or fictionalisations about the lives of the two men or the relationship between the two, such as the 2009 book, "The Fabulous Feud of Gilbert & Sullivan". P. G. Wodehouse makes dozens of references to Gilbert and Sullivan in his works. Wodehouse sometimes referred to Gilbert at length, and he based his Psmith character on Rupert D'Oyly Carte or his brother. Wodehouse also parodied G&S songs. In Jerome K Jerome's "Three Men in a Boat" (1889), a description is given of Harris's attempts to sing a comic song: "the Judge's song out of "Pinafore" – no, I don't mean "Pinafore" – I mean – you know what I mean – the other thing, you know.", which turns out to be a mixture of "When I, good friends" from "Trial by Jury" and "When I was a lad" from "Pinafore".
