The farmer explained that the bees just made honey and have never stung anyone.

The buyer felt unsure about the sale until he proposed that he be tied to a nearby tree, naked, overnight. If he was stung once he would get the farm for free, but if he wasn't stung then he would pay the farmer double the price.

The farmer agreed and tied the now naked man to the tree.

The next morning the farmer saw the man leaning over and very pale.

"Oh no!" the farmer thought, "He got stung and now I have to give him the farm!"

As he reached the man he gently shook him and asked where he got stung and if he needed a doctor.

"No, no, I'm okay," gasped the naked man, "I'll pay you double for the farm, but doesn't that damn calf have a mother?"
