Amy: To the Neil-mobile!

Raj: This is so much better than watching TV like a muggle.

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

Sheldon: Are you sure your moth-like personality won't be drawn to this blazing fire that is myself?
Amy: More and more sure.

Penny: See, just now you expressed your feelings to my face. How come you could do that with me but not with Raj?
Lucy: I don't know your email.

Penny: It's like if you're dating someone you're not that into and then they break up with you. Then you want them more than ever.
Sheldon: I have no idea what she's talking about, but we're ganging up on you so I agree.

Stuart: Is make-up really necessary?
Raj: When somebody looks at your dating profile, the first thing they see is your picture. I just want to make sure you look fun and full of life, not like a body they just pulled out the river.

Sheldon: Boy, do I have to urinate.
Leonard: If only there were a solution to that.

Amy: Hey, I won the Nobel Prize in physiology. Then I used the money to buy Stuart's comic store and close it down, so Sheldon would pay attention to me. ... Not the worst idea.

Raj: Oh, the movie's not as bad as you thought?
Penny: No, it is. But I decided instead of complaining about it, I'm going to go in every day and give it my all.
Amy: Good for you.
Penny: Thanks. There's no reason why I shouldn't be the best bi-sexual, go-go dancer, slowly transforming into a killer gorilla, anyone's ever seen.

Bernadette: Now there's two of them.

Howard: You okay?
Amy: Why? Because my boyfriend's off playing choo choo with some weirdo.
Howard: Well, to be fair, they're both weirdos.

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

Raj: Who died and made you the king of moments?

Emily: If I saw you out with another woman, I'd be pretty upset.
Raj: Thank you. Not just for being upset, but for believing that could happen.
