I had an eraser from a mechanical pencil stuck in my ear for 9 years. I stuck it in there when I was 10, but was too embarrassed to tell anyone about it until I was 16. At that point, it became a weird sort of ice breaker. Unfortunately, when I was 19 it moved down my ear canal more and every tie that I bit down I could feel it pushing on my ear drum. The doctor didn't believe that it could possibly still be in there after 9 years, but the nurse flushed it out. Everyone was hilarious (handing pens and things to my then-boyfriend rather than me so that I didn't stick them in my ear) and it was an overall lovely experience.
