Extended Plot

Sheldon Cooper learns that his mother is worried about his not having any friends. He therefore gets a copy of How to Win Friends and Influence People from the school library and tries its methods on various students and teachers without success. Missy Cooper recommends that he try to make friends with other people who had checked out the book, since they too are looking to make friends. That also fails. He eventually meets a Vietnamese American boy named Tam who sees him with the book and they share how difficult it has been for them to make friends.


As they start speaking, they realize that they also share an interest in rocketry. Sheldon's mother is so happy, she insists that Sheldon invite Tam over for dinner, and lifts the ban on Sheldon's model rocketry hobby. The dinner turns awkward when Sheldon's parents exhibit cultural insensitivity as Tam tells them of his life story. After dinner, the boys' launch attempt goes out of control just as FBI agents arrive to ask Sheldon why he was trying to buy uranium.
