Clyde and the Unicorn
Once upon a time, there lived an eminently sensible earth pony named Clyde, who knew a frivolous unicorn. The unicorn earned much more money than Clyde did, due to his ability to enthrall and delight the townsfolk with his magic. However, the unicorn spent all that he earned almost as soon as the bits entered his coin-purse. Clyde noticed the unicorn drinking extravagantly one autumn evening, and gave him some advice.
"Sir unicorn," Clyde said. "You should save some of your bits for winter, when there will be few, if any, townsfolk wandering the streets to give you bits for your services."
"You're right," he said. "I'll start saving. Tomorrow. Or next week. Later. Another round, barkeep!"
Winter came around, and the unicorn had wised up too late. His savings ran out swiftly, and he knocked on Clyde's door for help, cold and shivering. Clyde opened the door, and the unicorn spoke. "Please help me, Sir Clyde. I should have listened to you in the first place, but I am but a poor fool who lacks discipline."
Clyde spoke. "Sir unicorn, I will feed you this winter. In return, you shall give me a portion of your bits next year, and I shall use those bits to keep you throughout the winter next year as well."
The unicorn gratefully accepted, and from then on, he was warm and well fed during the winter, and Clyde used the extra money to improve his farm.
The moral of the story is: Sometimes friends need more than just good advice.
