Penny and Leonard get into a big blow up over the fact that Penny visited a psychic and actually believes what the psychic told her. Leonard ends up apologizing and actually agrees to meet Penny's psychic. Bernadette and Wolowitz continue to date and are getting along swimmingly. In the mean time, Raj is feeling really left out, because he is the only one without a girlfriend. He bribes Sheldon to go to a mixer with him down at the University where they meet two really cute girls and one of the girls really likes Sheldon. They all go back to Sheldon and Leonard's apartment, and as Raj gets cozy with one of the girls, the other girl, Martha, suggests to Sheldon that she "tuck him in." This goes right over Sheldon's head and he totally rejects her advances and just replies, "Oh thanks, but the only person who tucks me in is my mother."
