In the season eight opener, Leonard and Amy go on a trip to Arizona to get Sheldon back. Meanwhile, Penny tries to get a job at Bernadette's company.
- Bait-and-Switch: While stuck in a car, Sheldon asks Amy to plug her ears so he can talk to Leonard in private. He then tells Leonard he's interested in a sexual relationship with Amy. A few beats later, he reveals it as a ploy to see if Amy really can't hear them, and then moves on with his true intentions.
- Comedic Underwear Exposure: When we first see Sheldon, he is only wearing a shirt and briefs because his pants were stolen along with the rest of his luggage.
- Important Haircut: Penny sports a shorter pixie haircut as part of a new adult look. Sheldon, of course, hates it.
- New Job Episode: With Bernadette's help, Penny applies for a job as a pharmaceutics representative.
