The Grasshopper and the Ant by Jean De La Fontaine
A Grasshopper gay Sang the summer away, And found herself poor By the winter's first roar. Of meat or of bread, Not a morsel she had! So a begging she went, To her neighbour the ant, For the loan of some wheat, Which would serve her to eat, Till the season came round. 'I will pay you,' she saith, 'On an animal's faith, Double weight in the pound Ere the harvest be bound.' The ant is a friend (And here she might mend) Little given to lend. 'How spent you the summer?' Quoth she, looking shame At the borrowing dame. 'Night and day to each comer I sang, if you please.' 'You sang! I'm at ease; For 'tis plain at a glance, Now, ma'am, you must dance.'
Clarifications: For the word comer, think visitor.
Summary: A hungry grasshopper comes to an ant, begging for food as winter approaches. The ant asks what the grasshopper did all summer while the ant was preparing for winter. The grasshopper admits with shame that she sang the summer away. The ant says, essentially, if you want food from me, you'll not only have to sing for it, you'll have to dance for it.
In other words, "Start humiliating yourself for my pleasure and I'll see if I have any food for you!"
Comment: This is a considerably more modern and less dry telling than Aesop's. Instead of life and death being at stake, humiliation is!
