Critics

 * Caroline Preece at Den of Geek! - How we get to the proposal isn’t in any way surprising or inventive, and has felt like a foregone conclusion for more than a season now, but the choice to include it here definitely piques my interest for a season eleven (and twelve) I can’t imagine anyone’s particularly excited for otherwise. But to have it as a cliffhanger makes little sense, because there’s not a reality in which Amy would say no. If the show really wanted to keep us on edge, a much better ending might be Amy turning him down before the cut to credits, with her reasoning something to be explained and resolved in the season premiere. It’d be cheap, but also perhaps a little more intriguing.

Quotes
Sheldon: Knock knock knock* Amy *knock knock knock* Amy *knock knock knock* Amy. (She opens her door, and is shocked at seeing him on one knee, holding his Meemaw's ring out to her in its box) Will you marry me?


 * Amy: I was offered a summer research fellowship at Princeton.
 * Sheldon: A fine institution. The place where Albert Einstein taught, and where Leonard got his PhD, so it may have gone downhill.


 * Amy: I gave you one job! Keep an eye on him. How hard is that?


 * Amy: Why didn't you tell me?
 * Bernadette: We didn't want you to worry.
 * Amy: Should I worry?
 * Penny: No, come on, it's Sheldon. Nothing is gonna happen.
 * Amy: That's what you said to me when I started dating him. And then five years later, bingo-bango, something happened.


 * Amy: I've been smacking that ketchup bottle for a long time. All she has to do is tip it over and point it at her fries.


 * Penny: Do you think living with Amy has somehow stirred up Sheldon's sexual appetite?
 * Bernadette: (grimacing with disgust) Ugh. How can you think that? Why would you even put those words together?


 * Leonard: Uh, so, Ramona, tell us about yourself. Do you, do you have a boyfriend?

Sheldon: Leonard, your wife is sitting right here. What are you doing?

Sheldon: I'm sorry you had to go through that.
 * Amy: In fact, that's when I started to really miss you.

Sheldon: You know you just split an infinitive.

Sheldon: So, tell me about your scalar dark energy experiment.
 * Ramona Nowitzki: Not 'til you tell me about your latest paper on quantum loop theory.

Sheldon: Oh. You must be one of those dessert before dinner people.


 * Amy: Did I? Are you gonna teach me a lesson?

Sheldon: I am. It is naughty to put an adverb between the word "to" and the verb stem.
 * Amy: What are you gonna do about it?

Sheldon: I'm going to admonish you.
 * Amy: Vigorously?

Sheldon: That's the only kind of admonishing I do.

Sheldon: I've learned some fun facts about New Jersey to help you make small talk. Would you like to know the state bird or the murder rate? They're both shocking.
 * Amy: Actually, I want to hear about you. How are things at home?

Sheldon: Well, I'm a lot less likely to see an Eastern Goldfinch or be murdered, I'll tell you that.Leonard: Wait, isn't she the grad student that used to follow him around?
 * Howard: Oh, yeah. Back before he hit puberty and grew man parts.


 * Penny: All right, then we agree. He's not making any moves, it's this Dr. Ramona chick.
 * Bernadette: Nowitzki. I Googled her, she's pretty cute.
 * Penny: Really? All I got from Leonard was the Toblerone bar had nuts.


 * Raj: Dr. Nowitzki. Good to see you.
 * Ramona Nowitzki: Good to see you, too.
 * Raj: May I join you?
 * Ramona Nowitzki: No.
 * Raj: Good to see you.

Sheldon: She's always been a huge fan of my work, and now she's doing research at Caltech.
 * Amy: Huge fan, you say?

Sheldon: Yes. I think you'd like her. She's extremely intelligent, just like you. Unlike you, she's tall, blonde and used to be an Olympic swimmer.

Sheldon: That may be true, but Dr. Nowitzki's just a friend. In fact, I wouldn't have even noticed she's a woman if she hadn't worn that bathing suit that highlighted her bosom.
