This is the shortest episode in the series.
When Amy tells Sheldon that it is customary to greet a familiar person in a restaurant, Sheldon responds that he has several restraining orders that say otherwise. At this point in the series, Sheldon has restraining orders from Carl Sagan, Leonard Nimoy, Stan Lee, Bill Nye and, as revealed in this episode, Zachary Quinto. It was stated in The Love Spell Potential (2013) that Sheldon was initially worried about Quinto being "the new Spock", but he apparently ended up liking him so much that he once followed him into a bathroom.
It is established that Raj's favorite movie is The Princess Bride (1987). Raj has previously shown his infatuation with this movie: in The Workplace Proximity (2013), he and Howard spent the night "giggling, eating cookie dough, and watching The Princess Bride"; when Howard told Raj to stop talking, Raj replied with "As you wish", which, in that movie, was a veiled way of saying "I love you". In The Workplace Proximity (2013), Raj imagined fencing to be like Game of Thrones (2011), but when Howard suggested Princess Bride, Raj immediately changed his answer to that. Later, Raj emulated the famous line from the movie, "My name is Inigo Montoya. You killed my father. Prepare to die."
