Sheldon can't sleep since he is totally preoccupied with solving a physics graphine problem. By association, Leonard and Penny can't sleep since Sheldon is continually bothering them. But Sheldon's sleep deprivation is making him more unusual than ever. He thinks he finally has the answer, not to the problem, but how to solve the problem. Much like Einstein did much of his best thinking when he worked in a patent office doing menial work, Sheldon believes he needs to get a menial job. A genius getting hired for a menial job is no easy feat, so Sheldon insinuates himself into a work situation of his own choice, much to the chagrin of one of his friends. Meanwhile, Leonard and Penny and Howard and Bernadette go on a double date to a disco roller rink. Raj is feeling left out, especially as it was his idea. On the other hand, Penny and Bernadette wish they hadn't gone.
