three soybeans

While going through his wife's dresser drawers, a farmer discovered
three soybeans and an envelope containing $30 in cash. The farmer
confronted his wife, and when asked about the curious items, she
confessed:

"Over the years, I haven't been completely faithful to you."

"When I did fool around, I put a soybean in the drawer to remind
myself of my indiscretion," she explained.

The farmer admitted that he had not always been faithful either,
and therefore, was inclined to forgive and forget a few moments of
weakness in his wife.

"I'm curious though," he said, "Where did the thirty dollars
come from?"

"Oh that, " his wife replied, "Well, when soybeans hit ten dollars
a bushel, I sold out!"
