Did you know that the man who originated The Katzenjammer Kids lost the rights to the strip, so he used the exact same characters in a new strip, The Captain and the Kids? The two comics competed with each other for years.
If I remember correctly (and there's no guarantee of that), both the Katzenjammer Kids and its competitor, Captain and the Kids, were based on an old German children's book,
Max und Moritz. Late 19th Century, I believe.
