Raj: Lucy?
Lucy: Hey, long time no see.
Raj: You don't know me very well, but each time you crawl out a bathroom window to escape my company, it chips away at my masculinity.

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.

Howard: A satanic fungus that looks suspiciously like Al Pacino rises from the forest floor and says, (Imitating Al Pacino) "You're playing D&D. You're playing D&D. This whole apartment is playing D&D."

Sheldon: I've never played Dungeons and Dragons with girls.
Penny: It's okay, honey, no one has.

Sheldon: Now, Penny, we don't consume alcohol during Dungeons and Dragons. It impairs our judgment.
Penny: Oh, this isn't alcohol. It's a magic potion that makes me like you.
Leonard: Double potion, please.
