Penny buys Sheldon and Leonard Star Trek transporter toys since she eats their food for free all the time. The guys both refuse to open the boxes and play with them, which Penny thinks is crazy. Sheldon has a dream with his Spock figurine convincing him to play with the toy. Sheldon gives in to the "toy" logic and plays with the transporter ... and breaks it. He decides to switch his broken toy with Leonard's mint-in-box toy. Spock visits him in his dreams again to convince him to do the right thing and take his broken toy back, but he doesn't. In the end, after many lies, Sheldon tells Leonard the truth.
