Bernadette: Besides, Penny and I are having a girl's night tonight.
Amy: Girls night, what does that entail?
Bernadette: Oh you know, girls get together hang out share girl talk.
Amy: I'm a girl.
Bernadette: Oh well maybe you could join us. I'll ask Penny.
Amy: No need, Penny and I are very close.
Leonard: You are?
Amy: Yes, In fact our mensies are synchronized.

Penny: Okay, help me out here. How does an archaeology professor get that good with a whip?
Howard: Maybe he took a class at the adult bookstore. That's how I learned.

Sheldon: No cuts, no buts, no coconuts.

Howard: We're looking for Sheldon, not Marmaduke.

Leonard: Would someone please turn off the Sheldon commentary track?

Sheldon: Under normal circumstances I'd say I told you so. But, as I have told you so with such vehemence and frequency already, the phrase has lost all meaning. Therefore, I will be replacing it with the phrase, "I have informed you thusly".

Penny: You know Amy, when we say we're having girl talk, it doesn't mean that we just have to talk about our ladyparts.
Amy: That's a shame. I had a real zinger about my tilted uterus.

Raj: Guys, I just did a quick calculation. Judging by the size of the theater and this line we may not get in.
(Sheldon wakes up and jumps out of his chair.)
Sheldon: What did he say?
Leonard: Nice going, Raj. I just got him down for his nap.

Sheldon: Hello. Well, this seems like an odd time to test my cell phone quality but go on. Test phrases. All right. Imatote. Ulba. Twad. All together? All right. I'm a total butt wad. Why are you laughing? Hello?
Penny: And that girls is how you make a phony phone call.

Sheldon: This is where we could've been if we hadn't stopped for dinner. This is where we could've been if Koothrapali hadn't ordered dessert.
Raj: I earned it, I ate all my brocolli.

Sheldon: I find zombies dancing in choreographed synchronicity implausible. And also it's really scary.

Sheldon: Knock Knock.
Leonard: Who's there?
Sheldon: Hugh.
Leonard: Hugh who?
Sheldon: Hugh guys ought to listen to me.

Sheldon: Well if it isn't Wil Wheaton, the Jar Jar Binks of the Star Trek Universe.

Sheldon: May I point out to you all that the screening is first come, first served?
Leonard: Relax, it's 5:00. The movie doesn't start till midnight.
Sheldon: Another way of saying that is: the movie starts at midnight and it's already 5:00. Let's go.

Sheldon: Trouble is my middle name Leonard. Actually it's Lee but I prefer Trouble.
Wil Wheaton: Oh, look who they let in.
Sheldon: Don't worry Wil Wheaton, I was just leaving. *Holds up the movie can and runs off*
