Confession of a wife...

Going through his wife's bedroom drawers, a farmer discovered three soya beans and an envelope containing $30 in cash. He confronted his wife, who promptly confessed. "Darling, over the years I haven't been completely faithful to you. But when I do fool around, I put a soya bean in the drawer to remind myself of my indiscretion."
The farmer admitted that he hadn't always been faithful either and, therefore, was inclined to forgive and forget a few moments of weakness. "Where did the $30 come from?" he asked.
"Oh that," his wife replied. "When soya beans hit $10 a bushell, I sold out."
