In the hope of winning the woman of his dreams, Amanda, lovelorn meter-reader Roger Wadell enrolls in a secret confidence-building class. The course's title takes on much more meaning when he discovers that his egomaniacal professor Dr. P also wants the same woman. They begin a fierce rivalry that quickly spirals out of control, their pranks and insults get uglier as they try to prove who is the ultimate guy's guy.
