Penny offers to cut Sheldon's hair as she used to cut her brother's hair, but he refuses. A week later, Sheldon has still not got his haircut and on Penny's advice, decides to relax his regimented lifestyle and "embrace the chaos". He begins to do things he never used to do before, like wearing his Tuesday pajamas on Thursday night and playing bongos at 3 am. This wakes Leonard and Penny, who plead with Sheldon to stop playing the bongos, to no avail, and he leaves the apartment still playing them. The next morning, they find him asleep on Amy's couch. With Amy's vote of confidence, Sheldon agrees to let Penny cut his hair. Sheldon is impressed with the way Penny had cut his hair, but when she is trimming his neck, she shaves off the back of his head accidentally. Meanwhile, Howard goes for astronaut training in Houston to prepare for his space mission. He confides to Bernadette via webcam his experiences in training, which involved vomiting during Zero-G training and having a horrible survival test. Bernadette feels pity for Howard and rushes to Houston, where she quickly finds out that his mother is already there to take care of him.
