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: I'm sorry, shoes, but you have to go back.
Shoebox (Penny): But, Penny, we love you.
Penny: I love you, too, but you cost more than my rent.
Shoebox (Penny): But Penny, you look so good in us.
Penny: (To Amy) Damn it, the shoes are right!

Sheldon: Red is angry, yellow is frightened, green is jealous and blue is depressed. Perhaps we can assign a color to lonely.
Raj: Nothing rhymes with orange. Its probably lonely.
Sheldon: All right. Come in. You look positively orange with loneliness. No, I dont see that catching on at all.

Sheldon: There's no need to interact with me. I'm just here to observe.
