In "Die Geschichte von den schwarzen Buben" (The Story of the Black Boys), Saint Nicholas catches three boys teasing a dark-skinned boy. To teach them a lesson, he dips the three boys in black ink, to make them even darker-skinned than the boy they'd teased.

WARNING: Not for the illiterate.
As he had often done before,
The woolly-headed black-a-moor
One nice fine summer's day went out
To see the shops and walk about;
And as he found it hot, poor fellow,
He took with him his green umbrella.
Then Edward, little noisy wag,
Ran out and laugh'd, and wav'd his flag;
And William came in jacket trim
And brought his wooden hoop with him;
And Arthur, too, snatch'd up his toys
And join'd the other naughty boys;
So, one and all set up a roar
And laugh'd and hooted more and more,
And kept on singing, - only think! -
"Oh! Blacky, you're as black as ink."
Now tall Agrippa lived close by, -
So tall, he almost touch'd the sky;
He had a mighty inkstand too,
In which a great goose-feather grew;
He call'd out in an angry tone:
"Boys, leave the black-a-moor alone!
For if he tries with all his might,
He cannot change from black to white."
But ah! they did not mind a bit
What great Agrippa said of it;
But went on laughing, as before,
And hooting at the black-a-moor.
Then great Agrippa foams with rage,
Look at him on this very page!
He seizes Arthur, seizes Ned,
Takes William by his little head;
And they may scream and kick and call.
Into the ink he dips them all;
Into the inkstand, one, two, three,
Till they are black, as black can be;
Turn over now and you shall see.
See, there they are, and there they run!
The black-a-moor enjoys the fun.
They have been made as black as crows,
Quite black all over, eyes and nose,
And legs, and arms, and heads, and toes,
And trowsers, pinafores and toys, -
The silly little inky boys!
Because they set up such a roar,
And teas'd the harmless black-a-moor.
Here's an animation (WARNING: In German...but watching it, you'd still get the point)

Do you think this is racist? Or hilarious? Or a bit of both? One youtube comment called it a "racist anti-racist story"
