Think we've all been here

I would chew on this part in a weird way where I would sort of gently bite upward with my bottom teeth pushing the clip up. In the middle of class in college I was doing it and the whole thing came detached from the pencil and flipped around perfectly in my mouth to where is like bullseye’d the center of my esophagus while it was open apparently and it was like immediately halfway down past the point of no return. I freaked out and went to the emergency room and they took an xray even though I told them it was plastic and actually put me under to try and fish it out with a scope, but it had already made its exit from my stomach. Doctor didn’t seem that concerned, but said there was a small chance it could cause a problem, but that in all likelihood I’d shit it out without knowing it. I gazed at my turds intently over the next few days, but never saw it.
