Amy: I don't know what made me think tonight would be any different.
Bernadette: Well just the fact you got him up here says a lot. To be honest, I bet Howie $200 that it wasn't going to happen.
Howard: I'm going to the Lego Store to get a big-ass R2D2.
Bernadette: See, it's not just Sheldon, they're all idiots.
Howard: She's right.

Leonard: They've been in there for like half an hour.
Penny: Yeah, for future reference that's a while.

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

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.

Yvette: You're the owner?
Raj: Owner. Father. Soul mate. And, if anything happens to her, your (Leonard & Penny) worst nightmare!

Raj: Oh my God, Cinnamon, are you okay? I can't believe you two (Leonard & Penny). (To the vet) You do whatever it takes to save her life. If she needs any new organs I'll buy any dog necessary and scrap them for parts!

Bernadette: Now there's two of them.

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

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.

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.

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.

Raj: I don't have (Valentine's) plans, which is why I booked time on the big telescope that night.
Amy: An evening looking at the stars, that's still kinda romantic.
Raj: Except I'd be alone.
Amy: I'm trying to put lipstick on a pig here. Work with me.

Raj: Since you two are going to be around for Valentine's, would you mind watching Cinnamon?
Penny: You have Valentine's plans!? Which came out sounding way more surprised than I meant. Here, let me try that again. You have V..!? See, I can't do it.
