However, I did hear that there was more to the story. Not long after that the poor farmer did end up in dire straits and died. At the funeral they asked if anyone had something to say. A friend stood up and said, "Plethora" and then sat down. The grieving widow then turned to the friend and said, "Thank you, what you said means a lot!"
