A woman's husband dies. He had left $30,000 to be used for an elaborate funeral. After everything is done at the funeral home and cemetery, she tells her closest friend that "there is absolutely nothing left from the $30,000." The friend asks, "How can that be?" The widow says, "Well, the funeral cost was $6,500. And of course I made a donation to the church -- that was $500, and I spent another $500 for the wake, food and drinks -- you know. The rest went for the memorial stone". The friend says, "$22,500 for the memorial stone? My goodness, how big is it?" The widow says, "Four and a half carats."
