Hyaa! Hyaaa!!!

I'm working on a piece right now that JUST WON'T FINISH! I poke at it with this stick and that stick, trying to find one that will intimidate it into rolling over and DYING, but it just won't oblige. I'm about to start HITTING it with the sticks. (After all, what's 20+ years of martial-arts training for, if you can't apply it once in a while?)

Thing is, this piece is just lying there, panting wanly. So obviously not finished. But how to dispatch it, once and for all? HOW? HOW???
