Sheldon becomes jealous when Bert wins an award. Meanwhile, Howard discovers an old remote control figurine of Stephen Hawking he had made.
- Agony of the Feet: Sheldon hurts his foot with a rock when it drops while he was trying to throw it. He then hurts his other foot kicking said rock in frustration.
- Amusing Injuries: Sheldon goes through a series of them throughout "The Geology Elevation." First he drops a rock on his foot while trying to throw it, then hurts his other foot kicking it. Then he slips and hits his head on a water fountain while he was trying to punch it. And finally, he hurts his hand punching (or rather, karate chopping a la Captain Kirk) Burt for saying that he could do better than Amy.
- As Himself:
- Green-Eyed Monster: Sheldon is envious of Burt the geologist for winning the MacArthur Fellowship award.
- Let Us Never Speak of This Again: The guys promise not to let Howard know that Stephen Hawking would have liked a remote control toy of himself.
- Your Approval Fills Me with Shame: Howard shops around a Stephen Hawking remote control toy to see if others consider it offensive. Bernadette, Raj, Amy and Leonard all think it is, but it's Barry Kripke (who also wants to drive it into the women's restroom) thinking it's hilarious that convinces Howard that it is offensive.
