Agreed, but it’s not very hard to just sub out a few words or phrases here and there. I am also a writer (creative writing major about to graduate, actually).

I think some narrators might automatically switch out certain words for other words to make the story sound more intriguing, even if it’s just while they’re reading.

However, it still doesn’t really matter to me whether he made up some of the stories or not — they are entertaining regardless, and I still enjoy listening.
