What is the purpose of satire?  It is it effective?  Can it get you in trouble?  Terry Lindvall is the CS Lewis Professor of Communication and Christian Thought at Virginia Wesleyan College.  He writes about humor and in his latest book, God Mocks:  A History of Religious Satire From the Hebrew Prophets to Stephen Colbert, he explores the role of religious satire throughout history.  From Elijah to Alexander Pope to Robert Ingersoll and more, Lindvall introduces us those who tickle our funny bone while calling us out.
