I'd like to tell you a little story.  For the last few days, my kitchen has been smelling kinda funky.  But I didn't know why.  I had almost no trash in the trash bin, the sink was totally clean... "What's the deal?" I wondered.  So it was getting worse and worse, but I couldn't find the source.  I thought, "Oh boy-- something died in a wall, terrific."  But then I had a revelation.  I was in the shower this morning, going over how to explain the oil-burn on my left hand to my girlfriend in Japanese.  The previous night I had cooked some bacon for a BLT, and the oil splattered on me from the pan.  But I was thinking, "Will she believe that?  She knows I don't like bacon."  And I tried to rationalize it myself.  "Why did I eat bacon last night?  Didn't I have anything better to eat?  I know I didn't eat the fish yet.  But I don't remember seeing it in the fridge! Could it be in my backpack still?"  Keep in mind at this point I'm still in the shower, and I bought the fish on Wednesday.  When I finished my shower, I stepped out into the kitchen (yes, my shower opens directly into the kitchen).  I peered down at my innocent looking backpack resting peacefully on the floor.  I always use my backpack when I go grocery shopping, because it's easier and saves plastic.  So I open it up, and BAM! A cloud of the most horrific, nasally abrasive gas consumes my wet head.  I hesitantly reach in, and amid the caked on slime is the above pictured slab of molded fish.  It was hidden behind an inconspicuous flap.   Visually undetectable on Wednesday, but today an olfactory nightmare.  I set it in the trash, and snapped a quick photo because that's just what I do.  Now, being exposed to open air, my apartment smelled like the dorm room I shared with that baboon freshman year.  I took out the trash, but the smell lingered.  My backpack.  The slime.  The horror.  I tried to clean it; I set it in the bathtub with a pile of laundry detergent and scrubbed away.  But it is a lost cause.  As I  write this, it has been soaking for 16 hours to no avail.
