Howard: People change names on blogs to protect their privacy. Roger is Raj.
Raj: Oh, I always thought if I had a white name it would be Gavin.

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

Penny: What do you mean new roommate? What happened to Leonard?
Sheldon: The same thing that happened to Homo Erectus. He was replaced by a superior species.
Raj: I'm the new homo in town.

Penny: It's just, he's so passionate about so many different things. I just don't get that way. Do you?
Bernadette: Well, sure. I'm pretty passionate about science. I remember the first time I looked through a microscope and saw millions of tiny microorganisms. It was like a whole other universe. If I wanted to, I could wipe it out with my thumb like a god.

Sheldon: You don't know what it's like to feel completely frustrated. To have a desire build up within you and be denied any opportunity for release.
Amy: Yeah, sounds like a drag.

Amy: Missed one. Now your wish can't come true.
Sheldon: Lucky for you because I wished you were dead.
