A woman on her deathbed says to her husband, "I have a secret I want to tell you. Go to the closet and reach to the very back of the top shelf, and bring me the shoebox you find there."

Her husband returns with the requested shoebox, and opens it at his wife's instruction. He sees two crocheted doilies and a huge wad of cash. "What's all this?" he asks.

"Well," she begins, "when we first married, my grandmother had some advice for me. She said, anytime you feel yourself getting angry with your husband, don't yell at him, but sit down and crochet a doily instead. I thought that was good advice."

"Why, yes," agrees the husband, feeling rather pleased with himself. "I see there are only two doilies here. But where did all the money come from?"

"From selling all the other doilies."
