This week's episode opens with Charlie perusing a newspaper as Alan argues with his girlfriend over the phone. Alan apparently slept with the mother of his girlfriend because he was stoned, thinking they could make the color "purple" together. Alan does not know why she is upset, claiming that he was "molested and drugged by [her] mother, and [he's] the bad guy!" Charlie sits in the kitchen, basking in the security of his relationship with Chelsea. Then, Chelsea asks to use Charlie's phone, and she fumbles across some topless pictures of a girl named Rachel. She is immediately angered and asks if she knows if he is an engaged man, which he denies.
Chelsea then leaves and the men are left alone for bonding time. As the men chill by themselves, they discuss the issue of the boob picutes. Alan argues it is not so much about having the pictures as it is about cheating. Alan then decides to go pick up his son from his mothers.
As a relsult,Charlie was angered and does not want to spend his wekend with a boy of low self hygiene.
Upon arriving, the gentlemen are swarmed by Hegel who is not surving the pregnancy. He does not know how to handle his wife's hormones and elects to go with the boys.
After talking with the boys, Charlie discovers he deeply misses Chelsea and decided to get her back. Upon going to her house, he directly calls Rachel via telephone in front of Chelsea to show his sole devotion to her. Because he is hesitant to delete the nude pictures, chelsea remains frustrated and closes the door in his face.
