She was also interested in walking around my house in her underwear. Now the only one doing that is me.

Bert

She's younger and far more attractive than he is. Ha! They're copying you too.

Sheldon

Amy: I thought you were taking a break from women to focus on your career?
Raj: Oh, grow up.

Bernadette: What if she likes the people who work there more than us?
Howard: She already likes soap bubbles more than us.

My pants are missing, I don't remember anything. Penny, this is your youth, what do I do?

Sheldon

You know, I felt the same way about the spork. Solids and liquids handled by one utensil, that'll never work. Spoiler? Works.

Sheldon

Uh, oh. Someone's got two dates to the nerd prom.

Penny

Guys before this gets ugly, remember, the winner gets Sheldon.

Raj

Amy: I had a feeling you were using the wrong computational model, but I didn't say anything 'cause you're so sensitive.
Sheldon: Just because I'm easily bothered by light, heat, smell, sound, and the way birds look at me does not mean I'm sensitive!

Bernadette: Look, Raj just gets along with women.
Leonard: I know, but he was my friend first. It's like she's stealing him and they're having the best time doing all their dumb girly stuff together.
Howard: You sure you don't fit in? You sound like a catty bitch to me.

Amy: Number three, to avoid getting frustrated, we take built in breaks and award our successes with a small treat.
Sheldon: Oh that sounds fun. Now we're talking about real treats, right? Not Bible verses like my mother used to give me.

Leonard: Anyway, I figured I can hang out with my friends and have fun too.
Bernadette: Well if your idea of fun is riding in a minivan to Target for diapers things are about to get nuts.
