Summary
Howard and Raj are talking about having superheroes made in their own images. When they receive their dolls, they don't look like them. To create better looking superheroes, they decide to get a 3-D printer that makes three dimensional objects which is very expensive. Raj and Howard pose for their dolls and show them to Bernadette who wonders how there could be a Howard even smaller than the real one. After she learns how much they spent on the printer, she takes him off their joint checking account until he learns the value of money. Later, Howard is shown not eating lunch, saving up his lunch money to buy some Pokemon cards.

The university has forced Sheldon and Kripke to begin working together since they have similar projects which could lead to a Nobel Prize. Penny and Leonard come to the apartment and find Sheldon very upset about working with Kripke. Sheldon and Kripke exchange research papers and Sheldon discovers that Kripke's is much better than his. Amy holds Sheldon to comfort him, which he seems to enjoy. After Sheldon fakes being sick with a high temperature, he goes into work meeting with Kripke. Kripke says that he understands since Sheldon is distracted by having a full-time girlfriend to sleep with. Sheldon doesn't correct him, and even starts getting macho about his sex life. Later at the apartment having dinner with Penny and Leonard, he tells Leonard to accept any statements from Kripke about Shamy's sex life. Penny asks Sheldon if he is ever going to sleep with Amy, because she wants that type of relationship. Sheldon admits that he has always had problems with human contact, but recently he has become more comfortable with touching Amy. He admits that he and Amy might eventually have sex, which stuns Penny. Later at work, he and Kripke are again trading sexual innuendo about their women.
