Penny: Where did you get a ring?
Leonard: I've... had it for a couple years, not important. Penny... will you marry me?
Penny: Oh, my God, yes.
Leonard: This would have been so much more romantic if you didn't have monkey hair on your finger.

Penny: We could get married.
Leonard: Come on, be serious.
Penny: I am.
Leonard: Why? Because I'm a-a "smart decision"?
Penny: Well, yeah.
Leonard: So I'm like a bran muffin.

Penny: Okay, it may look that way, but getting fired from that movie was the best thing that could have happened to me, okay? I finally realize I don't need to be famous or have some big career to be happy.
Leonard: Then what do you need?
Penny: You, you stupid Pop-Tart!

I hope it's just a sprain. I cannot walk into that ER with another video game injury.

Bernadette: How come the three of you never got an apartment together?
Leonard: We talked about it, but Howard was in a pretty serious relationship with his mom.
Howard: I lived with her to save money.
Raj: You didn't have to buy groceries because you were breast feeding.

Leonard: So, is that it? Are we engaged?
Penny: Yeah, I think so.
Leonard: All right.

Leonard: Penny and I have some big news.
Penny: We're engaged!
Raj: And I thought me having sex with Emily was gonna be the big news.

Sheldon: She's spent many nights here, and you're worried about preserving the myth of her virginity before the wedding.
Leonard: I'm not.
Sheldon: Good, because not only has that ship sailed, if it hit an iceberg, countless men would perish.

Leonard's Mom: Leonard, would it make you feel better to hear that your mother approved of your life choices?
Leonard: Yes, it would.
Leonard's Mom: Yeah. Well, you should work on that.

Leonard: I know his password, so I can track his phone.
Penny: You do that?
Leonard: Not always, but ever since he wandered off at the swap meet chasing a balloon, I get worried.
Penny: He can take care of himself. Look, we went over stranger danger and gave him that whistle.

Leonard: Sheldon...
Sheldon: Yes?
Leonard: I'm gonna miss you.
Sheldon: Of course you are.
Leonard: He just made that easier.

Leonard: So a few things don't go your way and your best decision is to ride the rails like a hobo?
Sheldon: I suppose it is. Except I have a credit card. And I refuse to carry my laptop at the end of a stick. And I'd sooner die than eat beans out of a can.

Oh, Bernadette, please play my clarinet.

Raj's poem

Sheldon: I'll have a diet Coke.
Penny: Can you please order a cocktail? I need to practice mixing drinks.
Sheldon: Fine... I'll have a virgin Cuba Libre.
Penny: That's... rum and Coke without the rum.
Sheldon: Yes, and would you make it diet?
