Selling Mules

Two farmers met one day and one asked the other if he wanted to buy the other's mule. 

"Yes, I think I might," the first farmer said.

"How much to you wan't for it," said the first farmer?

"Five dollars," said the second farmer.

"Fair enough, I'll take him." the first farmer said.

About a year later, the first farmer saw the second farmer and asked if he needed any mules. To which the second farmer, said yes, "I am planting more this year, would you sell me that mule I sold you last year," he said?

"Sure, the price will be ten dollars."

Needing a good mule, the second farmer paid the first farmer the ten dollars.

A year later, the second farmer needed some cash and asked the first farmer about buying the mule for $15.00.  He agreed and took the mule back.

This went on for years as the price rose well over $80.00.

Then one day, one of the farmers was asked to sell the mule to another farmer who lived well down the road.  He needed the money, a $100.00, and sold it to another man.

A few months later, the other farm came up to the farm to buy the mule.  When he discovered that the mule had been sold to someone else, he cried out, "Why did you sell that mule?  We were making a good living, selling him back and forth to each other."
