When the superannuated biblical Sarah learned that she would give birth to a son, she burst out laughing, and that son's name-Isaac-was forever a testimony to this moment of holy mirth. In The Mother of All Laughter: Sarah & the Genesis of Comedy, Terry Lindvall argues that there is a biblical place for laughter. At times, he lets truth be obscured by a good story (as when he cites the famous Neil Armstrong/"Mr. Gorsky" urban legend as fact), but he raises important points about humor for Christians.
