Welcome to the insane and rarified world of Professor Dr. Moritz-Maria von Igelfeld of the Institute of Romance Philology. Von Igelfeld is engaged in a never-ending quest to win the respect he feels certain he is due—a quest which has the tendency to go hilariously astray. In Portuguese Irregular Verbs, Professor Dr von Igelfeld learns to play tennis, and forces a college chum to enter into a duel that results in a nipped nose. He also takes a field trip to Ireland where he becomes acquainted with the rich world of archaic Irishisms, and he develops an aching infatuation with a Dentist fatale. Along the way, he takes two ill-fated Italian sojourns, the first merely uncomfortable, the second definitely dangerous.
