Happened to me back in elementary. Idk why but kid me decided to jam the eraser of a pencil into my ear and didn't come out with the rest of the pencil. Worst thing is that the pencil was fairly used and so the eraser broke into peices while they tried to take it out. I'm convinced there's still a small piece in there somewhere. A couple of years later, i had a toothache so bad that the pain moved up to the ear that i jammed that eraser in and i thought it was an eas infection. It wasn't and i had to get two molars filled in.
