Leonard is relieved to learn that Penny doesn’t want to break up with him after he rejected her marriage proposal, but is surprised to hear that she quit her job at the Cheesecake Factory to pursue acting full time. She gets upset with him when he seems less than enthused about the idea, but receives unlikely support from Sheldon, who spends the day with her after being forced to use his vacation days by the university. Sheldon believes that the only way to truly succeed at something is to devote one hundred percent of one’s efforts toward a goal, and Penny desperately needed to hear that. Meanwhile, Wolowitz and Koothrappali try to help Amy fend off the romantic advances of her awkward coworker, and Stuart accompanies Bernadette to a rival comic shop to find a replacement comic book for Wolowitz after she accidentally destroyed his copy.
