German kids misbehaved
In Germany, parents warn their children that if they don't finish their meals, it's going to rain. And indeed, in 2013 it rained, so much that some of central Europe's major rivers overflowed their banks. As shown in this image from 2013, the Elbe burst its banks following unprecedented rainfall. In the photo, muddy water covers the area around Wittenberg, in the German state of Saxony-Anhalt.
