Was watching a movie called "John Rabe," about a German in Nanking who worked to save as many Chinese as he could during the Rape of Nanking. Along the way, they show an American doctor singing an...ummm....unauthorized version of the Colonel Bogey March (The one in the theme of The Bridge over the River Kwai).
Did some research and it turns out this was actually in circulation in England during the war. There's some evidence it was written by a member of Britain's propaganda ministry in 1939, but regardless of where it started it was widely sung -- and widely modified. I've taken some of the variations and turned them into verses.
Hitler has only got one ball,
Göring has two but very small,
Himmler is somewhat sim'lar,
But poor Goebbels has no balls at all.
Verse two
Hitler has only got one ball
The other is on the kitchen wall
His mother was such a bugger
She cut it off when he was very small
Verse three
She threw it, into the apple tree
The wind blew it into the deep blue sea
Where the fishes got off their dishes
and ate scallops and bollocks for tea
