A wealthy labor economist had an urge to have grandchildren. He had two daughters and two sons and none of them had gratified his desire for a grandchild. At the annual family gathering on Thanksgiving Day, he chided them gently to bless his old age with their progeny. But I haven't given up hope, he said, Yesterday I went to the bank and set up a one hundred thousand dollar trust fund to be given to the first grandchild that I have. Now we will all bow our heads while I say a prayer of thanks. When he looked up, he and his wife were the only ones at the table.
