"Rhue"ful Author Accidentally Drops A-Bombs in German Schools: resulting in explosions of hilarity
Sometimes the best moments are the unplanned ones. Author Rhue is promoting Über uns Stille, which is partly memoir, and in which the author spends some time describing his youthful fixation with developing the perfect cannonball whenever a pool was handy.
It turns out that the German translation for cannonball is something like arschbombe. If you separate that into two words and change a few letters (substitute ss for rsch) you get what German students are hearing, and cheering, much to the chagrin of their teachers.
