A very long time ago, I bought one of those 3D puzzles that you can assemble into a grandfather clock—a working one at that. It takes a AA battery to run and you have to remove the back panel in order to get to it.
Well ever since I moved out that clock has kind of fallen into disrepair and yesterday I took some time to reassembled some pieces that fell off, rebuild the internal frame and change the battery. It was only when I was all done did I realize that a piece of the crown is missing! What a travesty!
But on the bright side, it runs again.
