An old pastor was going through a closet that he and his wife shared in their bedroom when he made an unusual discovery- an old shoebox that contained three eggs and a huge stack of one dollar bills. He asked his wife to explain, and after some hesitation she said, "Well every time you preached a lousy sermon over the years, I put an egg in the shoebox." He thought to himself, "Hey, that's not too bad, three bad sermons in all those years!"
He then said, "Well, what's with all those one dollar bills?" She said, "Uh well, every time I collected a dozen eggs, I sold them to the neighbors for a dollar!"
