My dad sang a version some seventy years ago, that went:

Oh there was a little deutscherman; his name was dunderbeck
he had a healthy appetite for sauerkraut and speck
he had a little butcher shop, the finest ever seen
and he got himself a patent to make sausage by machine.

Oh dunderbck oh dunderbeck how could you be so mean
now all the rats and pussy cats will never more be seen
They're all ground up in sausage meat in dunderbeck's machine
