Before she started hosting dinners for Indiana University's Sociology Department at Pans 'N' Pancakes, Robbie never imagined scholarly meetings could be so hostile. It's all due to Professor Charles Stilton, who seems to thrive on heated exchanges with his peers and underlings, and tensions flare one night after he disrespects Robbie's friend, graduate student Lou.
