Howard: You know, if he moves across the hall for good, Leonard could keep the stuff you don't like in Sheldon's old room. Solves everything.
Penny: That's a great idea!
Leonard: Ooh, maybe I could turn it into a gaming den.
Raj: That would be amazing.
Sheldon: Wait, wait, hold on - excuse me, that's my room.
Leonard: But you won't be living here.
Sheldon: But that's my room.
Leonard: But you won't be living here.
Sheldon: But that's my room.
Leonard: You guys might want to start eating. But you won't be living here.
Penny: Sweetie, once you stop paying rent, none of this is really yours.
Sheldon: But that's my room.
All: But you won't be living here!

Raj: I don't like bugs, okay. They freak me out.
Sheldon: Interesting. You're afraid of insects and women. Ladybugs must render you catatonic.

Sheldon: Scissors cuts paper, paper covers rock, rock crushes lizard, lizard poisons Spock, Spock smashes scissors, scissors decapitates lizard, lizard eats paper, paper disproves Spock, Spock vaporizes rock, and as it always has, rock crushes scissors.

Sheldon: Why are you crying?
Penny: Because I'm stupid.
Sheldon: That's no reason to cry. One cries because one is sad. For example, I cry because others are stupid, and that makes me sad.

Sheldon: Oh, I don't mind, I'm very good at complaining. If it were an Olympic sport, I'd complain about what a stupid sport it is and then I'd take home the gold.

Leonard: Superman's gone. My stormtrooper's gone.
Sheldon: Your Klingon word-of-the-day calendar's gone.
Leonard: I'd say "damn it" in Klingon, but that wasn't until next month.
Sheldon: It's "khoo-vakh".
Leonard: Khoo-vakh!

Leonard: Sheldon, this is not a big deal. It's a little white lie, everyone does it.
Raj: Not me, I'm a 100% honest in all of my relationships.
Howard: And how single are you right now?
Raj: Eating-cake-on-the-toilet single.
