Basically the point is to be funny about it or use it as a generator for a new topic. Skill at conversation is almost topic agnostic. Entertaining people can be entertaining about almost anything.
Again, this does not make sense. The point of an argument over trivia is... being funny? Maybe tell jokes or funny anecdotes instead?
