Summary
The university has required that the guys go out and promote science careers for women and Howard suggests that they go to his old middle school since he is an astronaut and their favorite alumni. Raj is seeking advice from the girls for his first date with Lucy. Bernadette suggests Disneyland and then the girls get more excited about going to Disneyland themselves instead of helping Raj. They ditch their jobs for a day, go to Disneyland and get made up as Disney Princesses. Bernadette is Cinderella; Penny is Sleeping Beauty and Amy is Snow White. At the middle school, Sheldon talks about Madame Curie who died of radiation poisoning from working with radium, Howard talks about the bullying he got while attending that school and Leonard obsesses over the scientists in his family who steered him from his real dream of being a rapper. Lucy and Raj have a texting date at a library since he can't talk to her. They enjoy themselves until Lucy flees at the end of the date. Back at their respective apartments, Leonard and Howard get turned on over their Disney Princesses, while Sheldon won't kiss Amy to "wake up the sleeping Snow white".
