Is Did Eric Clapton name his dog after Dr. Dolittle's Pooch? on-topic here?
I was reading Are questions about authors on-topic? and the only answer, which is at +18 votes states:
I would say that they would be on-topic, but only insofar as they relate to an author's literary life.
So I was thinking maybe the question about someone who is not even the author but only a fan of a book's character would not be on-topic. What relevance to literature does the fact that another well-known figure has named his pet after a character in a book?
Related Are trivia questions about authors on-topic?. Because if it is questionable if trivia about authors is on-topic, now we are looking at trivia about a person who is not even an author of a work. How many degrees of separation are we willing to go, especially with trivia? And note again that questions about authors are "supposed to" (as far as the +18 answer goes) relate to their "literary life".
