School for Scoundrels (2006)

Roger, a beleaguered New York City meter maid, is plagued by anxiety and low self-esteem. In order to overcome his feelings of inadequacy, Roger enrolls in a top-secret confidence-building class taught by the suavely underhanded Dr. P. Aided by his assistant, Lesher, Dr. P uses unorthodox, often dangerous methods, but he guarantees results: Employ his techniques and you will unleash your inner lion. Surrounded by a band of misfit classmates - Walsh, who's dying to move out of mother's basement; Diego, a punching bag for his hen-pecker of a wife; and Eli, a shy guy just looking for female companionship - Roger's confidence grows and he makes his way to the head of the class, even finding the courage to ask out his longtime crush, Amanda. But Roger quickly discovers that star students have a way of catapulting Dr. P's competitive side into high gear. Soon enough, the teacher sets out to infiltrate and destroy Roger's personal and professional life. Nothing is off limits for Dr. P, not even the object of Roger's affection. In order to show Amanda Dr. P's true colors, Roger must rally his new friends and find a way to beat the master at his own game. Written by The Weinstein Company
