Hidden Sunday work

In Germany it is highly frowned upon if you even consider working on a Sunday. The only way you can get away with working on your house is to spend the whole afternoon in the cellar with Ikea packages and instructions with pictures but no words.
At first the shelves were very wobbly, but then we found an extra little plastic packet containing anti-wobble devices (AWDs). So we dismantled the wobbly bits, inserted the AWDs and now they no longer wobble. Shame there aren't AWDs available for other aspects of our daily lives.
