Penny: Ah, it's nice having the place to ourselves, isn't it?
Leonard: Uh-huh. Now that Raj is working for Sheldon, I don't have to chauffeur him around anymore. Plus, yeah, with them working late so much, we get some privacy.
Penny: Mm-hmm. Hey, want to get a little crazy?
Leonard: What are you thinking?
Penny: Let's slide over to Sheldon's spot and make out.
Leonard: You are a dirty girl.

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Leonard: What am I supposed to do?
Penny: Err, keep your mouth off other women.

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

Leonard: I've always been a little confused about this. Why don't Hindus eat beef?
Raj: We believe cows are gods.
Sheldon: Not technically. In Hinduism, cattle are thought to be like God.
Raj: Do not tell me about my own culture, Sheldon! In the mood I'm in, I'll take you out, I swear to cow!

Sheldon: There's a fine line between wrong and visionary. Unfortunately, you have to be a visionary to see it.

Raj: I'm going to be deported. Sent home in disgrace. Exposed to the sardonic barbs of my cousin Sanjay or, as you may know him, Dave from AT&T customer service.
