The proverbial money-shot.  I was taking pictures last year in Cornwall for a project that involved scrambling around clifftops and abseiling into zawns.  On the last day of the trip I managed to drop the viewfinder for the mamiya 7 down this zawn whilst fumbling it out of the camera bag.  Despite looking like something you might buy on an unnamed internet marketplace for £6.99 it turned out to be worth £500, £350 of which the University declared me accountable for.  I've since paid £250 of this myself, managing to acquire the rest from the Uni's contingency fund.  Quite a sob story.  Anyway, this picture ended up the sole fruit of my misadventure, and as it happens there's a limited edition of 1 available for, you guessed it, £250.  Bargain.
