chunk: As its title suggests, the book is ostensibly Tristram's narration of his life story. But it is one of the central jokes of the novel that he cannot explain anything simply, that he must make explanatory diversions to add context and colour to his tale, to the extent that Tristram's own birth is not even reached until VolumeÂ III.
  Consequently, apart from Tristram as narrator, the most familiar and important characters in the book are his father Walter, his mother, his Uncle Toby, Toby's servant Trim, and a supporting cast of popular minor characters, including the chambermaid, Susannah, Doctor Slop, and the parson, Yorick, who later became Sterne's favourite nom de plume and a very successful publicity stunt. Yorick is also the protagonist of Sterne's second work of fiction A Sentimental Journey Through France and Italy.
