A surprisingly common form of Theme Naming is the practice of naming characters after real-life celebrities and famous people. One way this can be done is to give a group of characters a set of names which, when combined, form the name of a famous person. An advanced version gives a person the same first name as a famous person, and has their last name included as a middle name. Another variation is to give a group of characters the first names of a well-known group, such as a group of friends named John, Paul, George, and Richard/Ringo, after The Beatles.
