Das tapfere Schneiderlein (1964)

One morning, a tailor was sitting at the window sewing. A shopkeeper came by and loudly offered plum jam for sale. The little tailor spent his last penny to treat himself. But the sweet smell of plum jam attracted a lot of flies, and when the tailor struck, seven fell by the wayside. This deed seemed so remarkable to the little tailor that he made himself a belt on which it was written that he had killed seven in one go.
