Amy: You don't need to explain yourself to him.
Sheldon: (To Leonard) I don't need to explain myself to you!
Amy: You're sick of his nonsense and you're ready to move in with me.
Sheldon: (To Leonard) Keep the table. We don't use that space.
Amy: Damn it. I got cocky.

Amy: (About Sheldon) Why do I even try?
Bernadette: I'm going to fix this right now.
Howard: Okay, but just make it look like an accident.

Leonard: Cinnamon, guess who just did it "human-style".

Howard: Fun Fact: I'm going to jump off this train!

Penny: Should we take this little party to the bedroom?
Leonard: We don't have to. We have the whole place to ourselves.
Penny: Oh, that's true.
Leonard: In fact, if you want, we can do it right here on Sheldon's spot.
Penny: That is the least sexy thing anyone's ever said to me.

Penny: Aw, jewelry. Oh my God, Lakers tickets!
Leonard: It gets better. Instead of me you can take someone who will actually enjoy it.
Penny: You are the best boyfriend ever.
Leonard: Seriously, please don't make me go.

Penny: Don't be surprised if you find five chocolates missing and three gross coconut ones with a bite taken out. Came that way when I bought it.

Leonard: Ooh, flowers and chocolates? Somebody's trying to get me out of my panties.

Sheldon: I'm prepared to say I love it, as soon as I confirm there are no hobos aboard.

Raj: I'd like for at least one of us to see some action, so if you guys happen to have sex it's cool if she stays in the room.
Penny: Same goes for the two of you (Howard & Bernadette) with Amy.

Amy: Item 28 - Your Pet Name for me. Time is running out on this. You need to make a decision.
Sheldon: I submitted you a notarized list.
Amy: I'm sorry but "Gollum" and "Flakey" are not acceptable.
Sheldon: Well, you don't like Princess Corncob, you don't like Fester, you're just impossible to please.

Sheldon: Wow, I'm feeling the urge to hug you. And 1, and 2. All right, Gollum, we're good.

Sheldon: What are the sleeping arrangements? We've only been dating for three years. If we were to share a room people might talk.

Leonard: I'm not sure it's a good idea to take Penny to where wine comes from.

Sheldon: How many trains have you been on?
Eric: Tons. A box fell on my head at UPS six years ago. Now I just collect disability and ride trains.
Sheldon: Wow. Your life's amazing.
Eric: Not always. A box fell on my head at UPS six years ago. Now I just collect disability and ride trains.
