An elderly pastor was searching his closet for his collar before church one Sunday morning. In the back of the closet, he found a small box containing three eggs and 100 $1 bills. He called his wife into the closet to ask her about the box and its contents. Embarrassed, she admitted having hidden the box there for their entire 30 years of marriage. Disappointed and hurt, the pastor asked her, "Why?" The wife replied that she hadn't wanted to hurt his feelings. He asked her how the box could have hurt his feelings. She said that every time during their marriage that he had delivered a poor sermon, she had placed an egg in the box. The pastor felt that three poor sermons in 30 years was certainly nothing to feel bad about, so he asked her what the $100 was for. She replied, "Each time I got a dozen eggs, I sold them to the neighbors for $1."
