Calf's Mother?

A fella was in the market to buy some acreage. He found
just what he was looking for, but it was a little expensive.
During an inspection of the property, however, he found a
hive of bees. He told the owner that he was deathly afraid
of bees, and there was no way he could consider this piece
of land. The landowner assured him that the bees were
completely harmless, but the buyer would have no part of it.
Finally, the landowner made an offer. The buyer would allow
himself to be tied to a tree for an hour, nude, under the
nest. So sure of the friendliness of his bees was the farmer
that if ONE bee were to sting him, the farm would be his for
free. The buyer thought it over and decided it was worth the
risk.
An hour later, the farmer walked out to the tree and saw
the poor buyer slumped over in his bindings. Fearing the
worst, he ran up to him and asked him if he had been stung.
The city fella looked up and weakly said, "No, but doesn't
that calf have a mother?"
