It's revealed that Raj's middle name is Ramayan.
Sheldon: What exactly does that expression mean, "friends with benefits?" Does he provide her with health insurance?
Leonard: No! Look, imagine you maintained a friendship with someone you had sex with, but you were free to date whoever you wanted.
Sheldon: I'm sorry, I can't imagine any of that.
Wolowitz: There's no place for truth on the Internet.
Raj: (about Howard) Too bad he wasn't here for that hooker. She was exactly his type: a hooker.
Penny: Hang on, I think the emergency key is around here somewhere.
Sheldon: We have a bowl. Our keys go in a bowl. You should get a bowl.
Penny: So how did the beautiful mind of Sheldon Cooper forget his keys in the first place?
Sheldon: I left them in the bowl.
Penny: Calm down, I'll call the building manager, and he'll come open your door. Just eat your dinner here while you're waiting.
Sheldon: Eat my dinner in your apartment?
Penny: Yeah, why not?
Sheldon: (in thick Texas accent) Sure why not? And after the sun's down we can all pile in my pickup and go skinny dippin' down at the creek!
Sheldon: Thanks for letting me stay here.
Penny: Oh, you're welcome sweetie.
Sheldon: Okay, I'm sleepy now, get out.
Raj: We should have a plan in case one of us gets lucky.
Leonard: Okay, if I get lucky, I'll take her to my stately manor outside Gotham City, and if you get lucky, I'll sleep on the moon.
Raj: Sounds like a plan.
Sheldon: I'm homesick!
Penny: Your home is 20 feet from here.
Sheldon: 20 feet, 20 light years, it doesn't matter. It's in a galaxy far far away.
