1. In World War II, the Germans used "anti-officer crooked picture bombs": They left paintings on the wall, skewed to the side and rigged to explode when straightened.

(Although as Wikipedia says, the alternate explanation is that knitting a jumper takes so long that the relationship will be over before you're done making it.)
