Plot

The Wolowitzes' life gets complicated when Stuart starts bringing his new girlfriend home. Also, Penny and Leonard talk about starting a family while Koothrappali explores an arranged marriage.

After completing a survey to find out all they need to know about each other, Raj is going on a date with Anu, the woman his father set him up with. Despite Anu not quite being the type of woman he usually goes out with, desperate Raj may forgo his dream of romance solely to be married. Even before taking some of the survey themselves, Leonard and Penny already know that they are not the most compatible couple. But their answers to one specific question may place an impassable wedge between the two of them. While Penny and Raj turn to Bernadette and Howard with their problems, Bernadette and Howard can't understand why their friends wouldn't just take their sage advice. And now that Stuart and Denise are dating, Howard ad Bernadette aren't sure if they can handle the fact of Stuart having sex in their house.—Huggo

While partaking in a take-out dinner in Apartment 4A, the Wolowitzes mention that a house was for sale in their neighborhood. The Hofstadters could become their neighbors and become part of the home-owner and crying baby set. Amy objects and wants Penny and her hubby to be their neighbors. Sheldon doesn't want to move because he'd have to change all the name tags on his underwear. Leonard thinks that they are happy where they are for now. Penny figures that eventually they'll get a loft downtown, while Leonard wants something with a yard. Raj plans to get to know Anu better before they get married. Raj insists that arranged marriages have existed for thousands of years and that they each filled out questionnaires to see if they are compatible. Raj asks Leonard what Penny's dream vacation is; a Malibu beach house. Penny snaps that that is Barbie's dream vacation and that Raj should send them the questionnaire.

Howard and Bernadette are quietly reading in their living room though Bernie is really shopping on her cell phone which is hidden in her book. Stuart shows up with his girlfriend Denise. Stuart offers to show her his room which Denise quickly accepts. Bernadette asks Howard how he feels about the couple "doing stuff" in his room. Howard doesn't feel that anything will happen until they both start hearing the song, "Smooth Operator".

In Apartment 4A, Leonard is doing a great job painting Penny's nails. They next received the marriage questionnaire from Raj. Going through it, neither of them have a stated religious preference. Penny still thinks that she is pretty spiritual since she does yoga. Penny is close to her family, while Leonard wishes that he were farther. On the subject of kids, Leonard wants them and Penny says maybe "someday".

At dinner, Raj and Anu (Rati Gupta) both agree that they know each other really well after having read their questionnaires. Raj stumbles and Anu says that he's not good at dating. That is why he is having his father set up their marriage. Anu also wants to get married since she is 34 and wants to have kids. She is a hotel concierge and is very ambitious and wants to take over the hotel manager's job. Raj had been looking for a wife that was just like Sandra Bullock. Anu thinks that she is nice, but wants a guy committed to their relationship. When she learns that his last name is Koothrappali, she asks how he feels if she doesn't change her name.

Penny enters Bernadette's office all ready for lunch, though she is quite busy because Halley and Michael are making her fall behind in her work. Penny mentions that maybe she doesn't want kids. Bernie objects saying that they are amazing. Penny notes that she is contradicting herself. Bernadette explains that beforehand you don't think you want them and afterwards you know that you wanted them.

In the cafeteria, Howard asks Raj how his date went and then Raj asks him if he'd like to be his best man. Howard wants to know why he would marry someone he only just met. Raj feels that they are both nice so why not. Sheldon feels that Raj is doing the right thing bowing to a 3000-year-old authoritarian tradition. Howard still thinks that Raj knows nothing about Anu. Raj quotes four facts about her and then storms off.

Howard returns home unhappy that Raj is mad at him. Bernadette feels that Penny is also mad at her. The Wolowitzes wonder why their friends won't listen to them since they have a great marriage, great kids, great jobs and a great house. Next "Smooth Operator" starts playing again.

Back in the Hofstadter home, Penny asks Leonard about when she mentioned that they might have kids "someday." Leonard jumps to the conclusion that she is pregnant. "No," replies Penny several times. She then asks how he feels about not having kids. Penny doesn't want to change the great life they have now. Leonard says "Sure," with no conviction. Then he adds that they couldn't raise kids in the loft that she never told him about. He tries to leave, but can't get the door opened. After Leonard leaves he can be heard telling Amy that he's NOT mad!

While driving Sheldon to work, Sheldon is happy that they are having a quiet ride to work until Leonard mentions that Penny doesn't want to have kids, while Sheldon would rather not talk at all.

Howard approaches Raj who is eating alone in the cafeteria. Raj then asks if he is making a huge mistake having chosen a blueberry muffin. He insists that he is happy with his choice even though Howard's cinnamon roll smells delicious. Howard splits it with him. Howard apologizes, but wonders why someone who is so romantic would agree to an arranged marriage; however, if Raj is happy, then Howard will fully support him.

Amy storms into Apartment 4A, shouting "What the hell, Penny!" She wanted their kids to grow up together because she felt that no one else would be their friends. Penny says that they can make other friends and they'll be the fun Aunt Penny and Uncle Leonard who will give them candy, teach them swear words and tell them stories about how weird their mother is. Maybe Amy could live with that. Unfortunately, she had the dream that the two of them would breastfeed each other's children.

Howard comes into their bedroom and hops into bed to get romantic with Bernadette. "Smooth Operator" starts playing again. Howard tries to drown it out with their music, but only wakes up Michael.

Leonard comes home to Penny working in the kitchen. She fixed his favorite meal, an "In & Out" burger on a plate. The whole "no-kids" issue just took Leonard by surprise, and not in a good way. He always thought that he would have kids, and is now disappointed that it won't happen for him. There are a lot of other things that he imagined that he has never gotten like, a Nobel Prize or a working Batmobile. Though another thing he thought he would never have was a wife like Penny. Her phone rings and Penny's father Wyatt (Keith Carradine) calls asking her why he wasn't getting any grandchildren.

Getting drinks from the bar, both Raj's and Anu's parents were happy for them. Raj's parents even spoke to each other. Anu wants to go onto the next step toward a wedding. Themes and flowers? No. Finances and taxes. That was the theme of Raj's parent's divorce. Raj then wonders if they should get married since he is really a hopeless romantic. Anu seems great, but this was not the story he wanted to tell his grand-kids. Anu looks sad and calls him back. Anu tells him that he would make a great father and that he is tall enough that she can wear heels. She thinks that that is something worth fighting for. Anu then gets down on her knees and asks Raj to marry her. He joyfully accepts as the bar breaks into applause.

Walking down the street, Penny brings up the subject of things Leonard thought he would never have. Penny points to a Batmobile parked in front of them. Leonard is excited that she had bought him a copy of the 1960s series Batmobile. "No," replies Penny several times. The car had been rented for one day without insurance. Leonard jumps in driving off leaving Penny alone. Then he backs up, asks for Robin to join him and off they go together. "Na-na-na-na-na-na-na-na......Batman!"
