I used to keep a bag on my desk at work with a bunch of LY rod pieces from when I grenaded it at the 1000-ft. mark years ago. You could make a jig-saw puzzle with them.

Like another poster mentioned, the break probably started with a bolt, but by the time it was all said and done, it was a whole bunch of pieces, plus a broken camshaft, plus an effed-up block & crank, etc.
