Raj: I did the research. Tony the Tiger, Dig'em the Frog, Cap'n Crunch, Toucan Sam, Count Chocula, Trix the Rabbit, Snap, Crackle and Pop. Not one cereal mascot is a girl. It's a total breakfast sausage fest.
Leonard: Are we done with this?
Raj: Almost. Franken Berry, Boo Berry, Sugar Bear and the Honey Nut Cheerio bee, I believe his name is Buzz.

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.

Amy: I have a lab full of coked up monkeys with nothing to lose.

Sheldon: My father used to say that a woman is like an egg salad sandwich on a warm Texas day.
Alex: What?
Sheldon: Full of eggs and only appealing for a short time.

Sheldon: I don't see why I'm the one being persecuted here. Dr. Hofstadter, he was bragging about his sexual desirability to anyone who would listen. You know, and Howard Wolowitz, he spent two years using university resources building a six-breasted sex robot. Oh, and at the office Christmas party, I heard Rajesh Koothrappali refer to you several times as Brown Sugar.
Ms. Davis: Hofstadter. Wolowitz. And the last one was Rajesh Koothrappali?
Sheldon: Yes. No, yeah, but in his defense, that wasn't racist. He's also brown.
