Frim the murky recesses of my failing memory comes the verse:
"When Herr Goebbels says, "You'll get some meet next week"
Ve Heil! Heil! But ve vould rather eat
For to doubt Herr Goebbels would be indiscrete
So ve Heil! Heil! Und still don't get no meat."

And , as I dimly recall, the original film was called "Donald Duck in Nutziland"
