We've all heard someone called so-and-so the second and others called blah-blah-blah Jr. but what makes someone a "Jr" as opposed to a "II"? Thanks to Mental Floss' Big Question, now we know.
It seems a Jr. is generally the child of a living person they have been named for, while IIs, IIIs, IVs, etc. are all named for close relatives who may or may not still be alive. One particularly strange case that manages to combine both titles is that of George Foreman and his sons who are all named after him:
Of course, there’s always George Foreman, who has five sons named after himself. And since “Jr. Jr.” isn’t really a thing, George’s sons are George Edward Foreman Jr., George III, George IV, George V, and George VI. (Don’t worry; they all have nicknames.)
