School for Scoundrels is a 2006 American comedy film, starring Billy Bob Thornton and Jon Heder, and directed by Todd Phillips.
To overcome his lack of self-esteem, he signs up for a course taught by Dr. P where Roger and his classmates are constantly bullied by Dr. P and his assistant Lesher, who likes to use outrageous and unethical methods on them, including humiliation.
While participating, Roger begins to develop a sense of personal pride and finally asks Amanda for a date where he uses tricks he learned during the course.
He approaches her with a false story that he is a successful and child-loving surgeon whose wife has died, and Amanda, who is a voluntary caretaker for animals, is immediately attracted and starts dating him.
With the aid of Lonnie and classmates, he finally exposes Dr. P's duplicity, it's revealed that Dr. P isn't a doctor or surgeon (he wanted to use a defibrillator on Roger who just fainted, but was truly faking) and that his wife is still alive.
School for Scoundrels came in at #4 at the North American box office in its opening weekend, accumulating $8,602,333, before eventually grossing $23,947,685 worldwide.
