You really need to be reading this whole thing. This is a cute moment from Chapter 3; not sure if it's Obama or the reporter who doesn't know that it's dilithium:

"That's an interesting belt buckle," he said to Michelle, mischievously. She feigned offense and said, "I am interesting, next to you. Surprise, surprise, a blue suit, a white shirt and a tie." Obama grinned and bent down until he was almost at eye level with her waist. He jabbed a playful finger toward her belt buckle, and let loose his inner nerd. "The lithium crystals! Beam me up, Scotty!" Obama squeaked, laughing at his own lame joke as Michelle rolled her eyes.
