What is funny? When does something become funny? Cease to be funny? Christopher Miller is a best-selling author, college professor who asked himself these questions and set out to answer the in his very amusing book, American Cornball: A Laffopedic Guide to the Formerly Funny. Think Whoope Cushions, squirting flowers, college professors and countless others. These gags and foils for comedy used to make us roll. Now theyre . . . corny. Well done, Chris Miller.
