Some recent howlers from the pens of my students:

A guy called 'Hemmingway' apparently wrote 'The Great Gatsby'; the changing values of the *1920s* were inspired by new technology like the birth control pill, the bikini, and television; the Great Depression lasted for thirty years; and (more disturbingly) the '100% American' KKK banded together to fight against the new immigrants who were 'causing chaos' in urban areas. Sometimes I wonder if they're listening to the lectures at all.
