Things That Go 'Bump' In The Night

This is a little story that takes place early this morning.  I had just settled down in my bed, having put down my book and turned off my light around 2:30, and was in the process of slowly drifting off to sleep when I was awoken by a loud "bang".

I bolted straight up out of bed, and glanced at the clock — 3:00AM.  Stumbling across my my bedroom, I flipped on the light and looked to see if anything seemed amiss.  Everything seemed normal, so I went and asked Scott if he had heard anything, but he had headphones in and hadn't heard a thing. 

Well, maybe I imagined it.  So I went back into my room and was just about to turn off the lights again when I noticed blue stuff all over the wall behind my desk.  It rubbed off easy enough, and had no particular smell.  How very odd.  That's when I glanced down at my desk, and there, sitting next to my keyboard, was the culprit.  A Duracell 9-volt battery that had been sitting on my desk for the past couple of weeks had spontaneously exploded, blowing the back off it half off and spraying something all over the place.  I have no idea why it did that, but it certainly was unexpected.

No points today, I couldn't think of any decent explosion quotes.
