A Headache
Not everything on this list has to do with illegal substances or objects, sometimes it’s what the x-ray reveals that stuns the TSA. Take for example this man’s skull which has what seems to be a large worm or some sort of string object lodged inside.

What should a TSA agent do when they see something like this? Should they alert the man and explain to him that there seems to be a worm inside your head? We’re not sure if that’s the TSA’s job to tell you such things but we’re glad they found this one out of time, who knows, maybe they saved this man’s life.
