Standing outside the door is the closest that Howard's mother has ever been to apartment 4A in the entire series. Up to now, only Sheldon's mother, Penny's father and Leonard's mother have been inside. Raj's parents have only seen the apartment through a video call and have not been physically inside.
Another clause in Sheldon and Amy's Relationship Agreement that was signed in The Flaming Spittoon Acquisition (2011) is revealed: any visit to another place must be announced at least 72 hrs in advance, tire pressure must be checked, and the CDC should be contacted to check for the need of certain vaccinations at the destination.
It is revealed that Amy is from Glendale.
The title is derived from the conflict Sheldon faces regarding how to spend his weekend, since he wants to join the Star Wars online game marathon with the guys yet he had promised Amy that he would attend her aunt's birthday party and meet her family.
