#34 on the list of Things Mom Told You Not to Do: Don't eat glass.

Yesterday I decided to make half a peanut butter and jelly sandwich, using jelly that had survived an earlier crash of the jar. Though I had removed the obvious large pieces, for some reason it did not occur to me that maybe a tiny piece or two of glass would infiltrate the jelly itself. Oops. So while I'm watching a particularly interesting part of Battlestar Galactica, I feel a sudden and distinct CRUNCH on my far left back bottom tooth -- rather uncharacteristic of smooth peanut butter. My tooth now has a bit of a rough, jagged edge on one corner. Rather annoying to my tongue, but invisible. Lucky it wasn't one of my front teeth.
