The episode was watched live in the United States by 1.22 million viewers and received mixed reviews.
After discovering something terrible in the nuclear power plant, Waylon Smithers bribes Carl to keep what he has found quiet by giving him tickets to a Bob Seger concert.
He invites Homer to join him, and he leaves Marge to chaperone a field trip on a World War II battleship, to her dismay.
After the latter sneakily tricks the children into going to bed early, Marge realizes that Sarah is not who she seems and is hiding her mean spirited boisterous and bratty personality from the other mothers.
The other burglars, Erin and Bette, explain how, while they and Sarah were heisting a museum where Chief Clancy Wiggum was on duty, the fourth member of their team - Lindsay Naegle - betrayed them and had them arrested.
Marge turns out to be useful in the planning, pointing out that most of the entrances will be blocked by celebrities, fans and the paparazzi and they will need stylish costumes to blend in, so they recruit her for the heist.
Wiggum and Homer confront Fat Tony, accusing him of kidnapping their wives, but he denies doing so and also suggests that the two's disappearance may have something to do with their husbands' selfishness and absentmindedness.
Leaving Ralph in Fat Tony's temporary care, Wiggum and Homer search for their wives while realizing that they do not know them very well, but then see Marge and Sarah attending the gala on TV.
While attempting to stop Marge and Sarah herself, Naegle ends up tumbling down the long amount of stairs and is exposed by Erin and Bette and arrested for stealing other women's jewelry, allowing Marge and Sarah to escape publicly with the jewel, much to the surprise of Patty and Selma and their friends who are watching the gala back at the Simpson house.
[11] In a series of since-deleted tweets answering fans' questions, show runner Matt Selman addressed both the change in Sarah Wiggum's personality and the use of guest star Megan Mullally instead of regular performer Pamela Hayden.
