Was a man named Ethan Caldwell arrested after posing as a museum tour guide and inventing completely fake histories for every painting? No, that's not true: The story originated on an Instagram page known for posting parody stories. The story carries a disclaimer labeling the post as funny, comedy, satire and "for entertainment purposes only." There are no credible news reports of Ethan Caldwell being arrested for posing as a museum tour guide. An online detection tool rated the mugshot image used for the post as 99.9% likely AI-generated.

The post shared details of the fake story, presenting itself as to be a real news report:
BOSTON, MA -- A man was arrested after allegedly spending three weekends posing as a museum tour guide and confidently making up elaborate stories for unsuspecting visitors.
Authorities say 34-year-old Ethan Caldwell purchased a lanyard online, wore a dark sweater, and simply began leading groups through the museum whenever actual tour guides were occupied.
