This story reminds me of working at Christmas with my sister doing commercial decorations. We had thousands of little red birds that always moved around on garlands while moving from the shop to set up requiring us to readjust everyone of them.
Once all install was done, we'd open a pack of birds at the workshop, take a hammer and red bird to the table and then beat it's little head off!
Since your hammer works ok therapy is what I would call it. :)
