I don't really know who Nathan Bartlett is in this context. He could be an ordinary person whose story is being told, or perhaps he's someone with a unique or remarkable story.
The names John Doe and Jane Doe are typically used as generic names for unidentified individuals. Without further details, it's difficult to tell the real story. It could be a story about two ordinary people in a small town, or perhaps they are used in a legal or mystery - related context where their true identities are being concealed for some reason.
Well, usually when we hear 'John Doe', it's more of a fictional or anonymous reference. But there might be rare cases where it refers to an actual person if it's in a very specific and local context that we don't know about.
The story of Nathan for You is fictional. It's designed to be humorous and engaging, not based on real events or people. The characters and situations are made up to entertain the audience.
Since there's not enough information about which 'John Doe real story' is being asked, it's difficult to give a very detailed answer. However, it could also be a story about a John Doe who was involved in a historical event. Maybe he was a witness or a participant in a significant local or even national event, and his actions or experiences during that time are what make up the 'real story'.
