Sheldon's assistant, Alex, flirts with Leonard a little more openly, and he finally picks up on it. Leonard is intrigued by the prospect of being liked by two women at the same time, but he has no feelings for Alex whatsoever; he just likes the attention. When he discusses how to handle this issue with the guys, Sheldon immediately voices his displeasure with the scenario, feeling that Alex should focus on his work alone. Sheldon covertly tries to get advice from Penny, Amy, and Bernadette about what to do, but Penny figures out that he's referring to Leonard and Alex and gets irritated. Sheldon tries to talk to Alex about it directly, but his suggestions come across as completely inappropriate and wind up getting him sent to Human Resources. While there, he dishes out dirt on some of the inappropriate things the other guys have done in the past, and they all get in trouble. In the end, Sheldon is forced to take an online sexual harassment course, and Leonard smoothes things over with Penny.
