Sheldon hires Stuart (Kevin Sussman) to spend the day with Amy when he'd rather go to a movie screening. Also, Leonard's mother, Beverly (Christine Baranski), comes to Pasadena and Penny struggles to make a connection with her, eventually planning a redo of her and Leonard's wedding.
Episode Tropes:
- Obnoxious In-Laws: Beverly towards Penny, although its mostly because she's sore about not getting an invitation to her own son's wedding.
- Shout-Out:
- Penny and Sheldon test each other on knowledge, including recognizing Kardashians and Bill Nye.
- Sheldon has more answers than questions about the Avengers movie.
- What the Hell, Hero?: Amy (through Stuart) calls out Sheldon for being a jerk again.
