Penny: I mean really, what's so great about being grown up?
Bernadette: Well for starters, we'd be splitting this check three ways.

Raj: Emily, your face is like a precious Dew-kissed flower.
Amy: Wow.
Raj: I know. Powerful stuff, huh?
Amy: No. You're supposed to be yourself. Not all desperate and creepy.
Raj: Okay, I'm getting some mixed messages here.

Sheldon: I should let you know the world has changed since you were a young woman. It's not all sock hops, soda jerks and segregation any more.
Mary: How old do you think I am?

Amy: I'm proud of you, Sheldon.
Sheldon: I'm proud of me, too. I've done all my research, I conducted an informal poll, and I've arrived at the rock solid certainly I've made the right choice.
Amy: Well, that's got to be a good feeling.
Sheldon: Oh, it is. Although ...
Amy: Oh crap!

Sheldon: Please don't take my looking forward to Leonard coming home as criticism of you in his absence. That criticism will come later in your report card.
Penny: Yeah, I didn't stay for the detention. I'm not going to read the report card.

Sheldon: That's curious. If there's no one here, why are there two glasses of wine on the table?
Penny: Oh, well you know. I've got two hands and a bit of a drinking prolbem.
Sheldon: Of course. Ask a silly question.

Howard: This man (Raj), held my breast the other day and I love him for it.
Raj: A little loud, dude.

Amy: When you told me I was going to be "losing my virginity", I didn't think you meant showing me Raiders of the Lost Ark for the first time.
Sheldon: My apologies. I chose my words poorly. I should have said you were about to have your world rocked on my couch.

Penny: Aww, what horrible thing are you trying to make up for?
Howard: Just putting something in the bank for what horrible thing I do next.

Amy: So what tools did you bring?
Howard: Everything we need to make jewellery moulds. Here's some silver, a crucible, and an acetylene torch to melt it down.
Penny: Ooh, that looks fun.
Bernadette: Maybe you should master glue before you move onto fire.

Raj: Why would you push a cow over? They're sacred.
Penny: Oh, stop it. I've seen you eat like a million hamburgers.
Raj: Hey, an animal can be both sacred and delicious.

Amy: I can't believe Penny's married to Zack.
Raj: I wonder what she saw in that guy.
Bernadette: I don't know. He's sweet. He's tall. Handsome.
Amy: Broad shoulders. Good hair.
Raj: Hmm, I wonder what she sees in Leonard.

Sheldon: But none of you know what this is like. Being celebrated for something you wish you never did.
Penny: You clearly haven't been with me at Mardi Gras.

Amy: That's very nice, but I have a boyfriend.
Bert: That's what they all say. You just don't want to go out with me because I have an off-putting personality.
Amy: No, that's not true. My boyfriend has an off-putting personality, too. Like way worse than you.

Leonard: Were you seeing other men?
Penny: No.
Leonard: Aren't you going to ask me?
Penny: Come on, really?
