Today I ate the staple

Picked up a couple pieces of cake today, real nice looking. Two chocolate and custard topped slices and they came in a small see through plastic clam shell box. One side of the box is hinged of course and the other side was secured by a tiny little staple. I popped the box open and took a big bite out of the cake, delicious!  It was right as I was swallowing that I noticed the little staple was now missing from the lip of the box. In that brief instant I thought it probably flew off when I popped the box open and it was now on the floor somewhere. In the same instant as I was swallowing I felt it go down my throat.   Immediately I froze and wondered if maybe I could cough it back up. No, its too late, that tiny little staple had gone done already. So now I sit here and wonder, will it puncture my intestines on its way through my system ? Will I need to go to the hospital ?  Will it stab me in the ass upon making its exit?  I figure I have another 8 hours or so until I find out what will happen.
