Critics

 * Oliver Sava of The AV Club gave the double-premiere a B+.


 * Dhruv Rao from The DR Club gave both the episodes a B.


 * Jesse Schedeen of IGN:*…the focus was on breaking the rest of the group into pairs and sending them on different misadventures together. I enjoyed that these pairings were slightly less traditional. We rarely see Amy and Bernadette interact without Penny completing the trio…And yes, we've seen episodes focused on Sheldon pestering Penny before, but the dynamic shifted slightly as Sheldon became the one desperate for companionship…All three stories held their own, though I enjoyed the Bernie/Amy portion the most. It was nice to see these two off on their own for a change and outside the shadows of their significant other…The fact that Sheldon reciprocated Penny's hug at all is a sign of how close the two have become over the course of six seasons…. this wasn't a bad start by any means.

Trivia

 * Amy and Bernadette attract the attention of two other guys without the gorgeous Penny around.
 * Each girlfriend finds themselves liking the guy which is closer in appearance to to the other friend's fellow.
 * When Sheldon says that watching Clash of the Titans was causing Penny nightmares, he had probably watched it himself since the Kraken that attacked Leonard in his nightmare is seen in that movie. Also, Sheldon previously mentioned Kraken in episode "The Date Night Variable" (S6E01) by citing the line "release the Kraken!" from  Clash of the Titans.
 * Amy calls Sheldon her "Sweet Baboo" which was also 's pet name for in the.
 * The sailor hat that Leonard promised to give Sheldon is fulfilled in the next episode "The Deception Verification" (S7E02).
 * Leonard must have learned Morse Code because in "The Cooper-Nowitzki Theorem", Leonard claims not to know Morse Code.
 * In her movie clip, Penny does not look like she did in the pilot since that movie was filmed over 10 years before when she first came to California.
 * Like showing his colleagues Penny's old topless movie, in "The Bakersfield Expedition" he took his picture with Penny to prove to people how beautiful his girlfriend was.
 * Leonard has facial hair again; the first time was in "The Electric Can Opener Fluctuation", which also involved a scientific expedition to a remote corner of the world.

Quotes
Sheldon: Welcome to the exciting world of 3-D chess.

Penny: Why don’t you admit you only want to play this game because you always play with Leonard and you miss him?

Sheldon: You over estimate his significance in my life.

Penny: Mmm.

Sheldon: Do I miss how he makes a face on my toaster waffle with syrup. No. Do I miss the way he fixes the zipper on my jacket when it gets stuck? I don’t think so. Do I miss how we say good night to each other through the walls of our bedroom using Morse code? {Knocks his answer in Morse Code].

Penny: OK, I get it. I get it. You’re an emotionless robot.

Sheldon: Well, I try.

Raj: Do you know I recently read a fascinating article on infidelity among penguins.

Mrs. Janine Davis: OK.

Raj: So if the fact that your husband left your husband makes you feel unattractive, just remember penguins get cheated on and they’re still adorable.

Howard: It was better when you couldn't talk to women.

Bernadette: [Toasting] To the advancement of science.

Amy: And to the sick and dying who make it possible.

Penny: This is ridiculous, why am I upset just because he's off having a good time?

Sheldon: Well, perhaps you're obsessively picturing him engaged in drunken coitus with another woman. [Penny stares at him angrily.] Is that it did I get it right?

Bernadette: Good night.

Amy: Mm-hmm. It was rather flattering to have strangers send us drinks.

Bernadette:Yeah, that felt nice.

Amy: Maybe tomorrow morning we put on some hot pants and see if we can score us some free omelettes.

Bernadette: So, hypothetically, if, if we were to have gone with them, which one would you have picked?

Amy: I think I would have gone with the short one with the goofy haircut.

Bernadette: Oh, good, ’cause I liked the tall thin one. He seemed intelligent, kind of a loner, maybe a little sexually inexperienced, like I’d have to teach him a thing or two.

Amy: Not my guy. I caught him staring at my rack. It’d be nice to be with a man who wants to know what’s underneath my cardigan. FYI, it’s another cardigan.

Bernadette: Your short sexed-up guy kind of sounds like Howard.

Amy: Your brainy virgin kind of sounds like Sheldon.

Both: Good night.

Penny: No. Come on, let’s talk about our lives. Tell me something about you I don’t know.

Sheldon: I own nine pairs of pants.

Penny: Okay, that, that’s a good start, but I was thinking maybe something a little more personal. Sheldon: I see. I own nine pairs of underpants. Penny: How about I go first?

Sheldon: But I don’t want to know how many underpants you own. Although, based on the floor of your bedroom, I’d say it’s a thousand.

Penny: Okay, look, here’s something people do not know about me. When I first moved out to L.A., I did a topless scene in a low-budget horror movie about a killer gorilla. Ugh! After I did it, I felt so ashamed. Thankfully, that thing never came out.

Sheldon: I've seen that. Yeah. Serial Apeist. Howard found it online the day we met you.

Penny: Oh, God.

Sheldon: And it was literally the moment you walked out the door. But I see the type of personal revelations you’re going for. Okay, here’s one I thought I’d take to the grave.

Penny: Okay.

Sheldon: Hmm. A while back, YouTube changed its user interface from a star-based rating system to a thumbs-up rating system. I tell people I’m okay with it, but I’m really not.

Penny: That’s your big revelation?

Sheldon: Yes. Whew, I feel ten pounds lighter.

Leonard (on board boat, at a party, dancing): Excuse me, ladies, my pants are buzzing. North Sea, how can I kelp you?

Penny: Leonard?

Leonard: Penny? Hey, it’s Penny. Everybody say hi to Penny.

Everybody: Hi, Penny!

Penny: Wow, it sounds like you’re having a good time.

Leonard: Best time of my life.

Sheldon: Isn't it five thirty in the morning there?

Leonard: Is it? Hey, everybody, it’s five thirty in the morning!

Penny: Uh, okay, well, we were just calling you because we were missing you.

Random voice: Iceberg!

Leonard: Uh-oh, hang on.

Sheldon: Are you in danger?

Leonard: No, it’s a drinking game. Whenever we see an iceberg, we take a shot!

Everybody: Berg! Berg! Berg! Berg! Berg! Berg!

Bernadette: This is fun, we never really get to talk shop with Penny around. We usually just end up talking about boys.

Amy: Which is fine, but it’s nice to mix it up with a little intellectual conversation.

Waiter: From the two gentlemen at the bar.

Amy: Oh, my gosh, boys bought us drinks, boys bought us drinks. Thank you, thank you, thank you so much.

Bernadette: Be cool.

Amy: You be cool. Guys are hitting on us, and not just to get to Penny.

Bernadette: You’re right. Thank you.

Raj: You know, I recently read a fascinating article on infidelity among penguins.

Mrs Davis: Okay.

Raj: So if the fact that your husband left you makes you feel unattractive, just remember, penguins get cheated on, and they’re adorable.

Sheldon: Do I miss how he makes a face on my toaster waffle with syrup? No. Do I miss the way he fixes the zipper on my jacket when it gets stuck? I don’t think so. Do I miss how we say good night to each other through the walls of our bedroom using Morse code? (Taps out "No" in Morse code on the table)

Penny: Okay, I get it, I get it. You are an emotionless robot.

Sheldon: Well, I try.
