This Book is referred to by Them, Robot part of The Simpsons Season 23
After Mr. Burns replaces all human employees with robots, Smithers is working as a substitute teacher. He is pelted with spitballs while standing at the chalkboard, and is so upset with the students that he tells them they will not be reading 'Death in Venice' after all. Later in the episode, books are thrown at the robots, who have now turned against humans. One of the books thrown is 'Death in Venice'.
Death in Venice is about a great writer suffering writer's block who visits Venice and is liberated and uplifted, then increasingly obsessed, by the sight of a stunningly beautiful youth. Though he never speaks to the boy, much less touches him, the writer finds himself drawn deep into ruinous inward passion; meanwhile Venice, and finally the writer himself, succumb to a cholera plague.
