The Big Bang Theory Episode 6.18 The Contractual Obligation Implementation

Sheldon, Wolowitz, and Leonard are forced to volunteer on a committee for the university, but Sheldon hates nearly all of them and doesn't want to put forth any extra effort. They wind up joining a committee that encourages women to get involved in the sciences and go to speak at Wolowitz's old middle school. The guys have problems relaying their passion for science to the school girls, so Sheldon calls Bernadette and Amy, who give a rousing speech to the attendees via phone. Koothrappali has been texting Lucy nonstop, since texting makes him less nervous and he comes off as more charming. He decides to take her to a library, where they can text back and forth instead of talking, and the date goes very well. Meanwhile, Penny, Amy, and Bernadette play hooky from work to get princess makeovers at Disneyland.
