There's some crazy stuff out there. My favorite are guys that come in with a "foreign object" in their rectum. LOL
Me: "Sir, how did that get up there?"
Him: "I fell on it"

Me: "Well, OK. Exactly why were you checking the "toy" drawer while your wife was out of town?"
Him: "She doesn't know about it."
Me: "She will now."

Classic x-ray conversation!
There was a news story in our area of a guy falling and having a piece of iron rebar pass right though his skull, went to the hospital because he had a "headache"
I think I read about that some years back, if it was the same incident I'm thinking of they apparently learned a lot about how the brain functions from it. Saw something about it on the Discovery channel.
I had friend that was doing clinicals for x-ray and he told me that this young woman, I think he said she was 20, had come in complaining about having a pain in her hand. When they imaged her hand the found a .22 bullet that had apparently been lodged in there for years. She claimed to have no memory of getting shot. He's a pretty trustworthy guy so I don't doubt him, but surely that's not something you'd go without noticing.
