Raj: Ah, yes, online gaming addiction. There's nothing worse than having that multi-player monkey on your back.

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.

Raj: What's with him?
Leonard: Penny is keeping him up at night.
Howard: Me too. But probably in a different way.

Leslie: Hello men. Sheldon.

Sheldon: Sheldor, back online.
Penny: What's AFK?
Sheldon: AFK. Away from keyboard.
Penny: Oh, I see.
Sheldon: What does that stand for?
Penny: "Oh, I see"?
Sheldon: Yes, but what does it stand for?
