Amy: And rolling.
Sheldon: Hello. I am theoretical physicist, Dr. Sheldon Cooper, auditioning for the role of Professor Proton.
Now, excuse me while I get into character. (Turns around and back. In the same monotonous voice) Hello, I am Professor Proton.

Leonard: I want to know, why aren't you proud of me?
Beverly Hofstadter: Well, isn't the real question, "Why aren't you proud of yourself?"
Leonard: No, that is a question - and I ask it a lot - but let's stick with the one I asked you.
Beverly Hofstadter: But why do you think I'm not proud of you?
Leonard: Because you never say it. But two days into chatting with Penny, and you can't stop telling her how great she is.
Beverly Hofstadter: She is great. Honestly, of all of my children's spouses, she's the one that I'm most impressed by.
Leonard: Seriously?
Beverly Hofstadter: Yes. She's confident, she's thoughtful, and she never complained about you once. I know what kind of strength that takes.

Clerk: Here's your license. Now, if you wait over there, we'll call you when the officiant's ready.
Sheldon: Do we need a blood test?
Clerk: No.
Sheldon: Well, then, how will you know whether or not we have syphilis?
Clerk: I'm gonna go out on a limb and say you don't have that.
Amy: Okay, Sheldon, you officially exceeded the number of times I hoped to hear the word "syphilis" on my wedding day.

Howard: Now you're gonna want to slowly switch lanes.
Sheldon: Why?
Howard: Because there are only two, and you're not in either of them.

Sheldon: Instead of being in charge, I can be the vocal opposition, criticizing and badgering the president at every turn.
Amy: I think you'll be really good at that.
Sheldon: Me, too.
Leonard: I think I made a huge mistake.
Penny: Me, too.

Raj: All I'm saying is before you attack Ruchi, maybe you should take a long hard look in the mirror, because you know what you'll see, apart from radiant skin and luxuriously thick hair? Hypocrisy!
Bernadette: It is thick.

Penny: Now, why don't you go wash up, and we'll call you when dinner's ready.
Sheldon: Okay. (Sheldon leaves)
Leonard: (surprised) What did you do? Are you a witch?

Leonard: That's amazing.
Penny: I know. But, you know, it's only birth to five. What do we do when he turns six?
Leonard: Take him to the zoo and leave him there.

Howard: She's actually been keeping herself busy doing wedding research for you.
Amy: Oh, she-she doesn't have to do that.
Howard: She wants to. After all, you were her maid of honor.
Amy: Sheldon, tell your funny story about pretzels.
Sheldon: Oh, right. Yeah, oh, yeah. Did you know that we've been thinking of having pretzels at our wedding? Hmm? No, no. No, no, no, no, no. I'm sorry. No, rhinos. We're having rhinos at our wedding.
No! (stammers) I got to go.

Sheldon: All right, you ready for your next one? Just a warning, this one's a little annoying. (imitates a high-pitched siren)
Leonard: Let's take a little little break, I'm getting a headache.
Sheldon: Aw, right in the middle of our fun game.
Leonard: Yeah, weird.

Sheldon: Uh, uh, hold on. Hold on. First, we have to read the minutes from last month's meeting. Amy, would you do the honors?
Amy: Why not? "Saturday, March 3rd.
7:05, meeting called to order.
7:06, president gets shampoo in eye.
7:07, meeting adjourned."

Sheldon: Neither of them will be the actual cake. I'm just using it as a bargaining chip to get Amy to agree to the whole wedding party getting rings and us getting one ring to rule them all.

Penny: It was a long time ago, we were broken up.
Raj: Which breakup was that? Was that the Saint Valentine's Day Massacre?
Howard: No, no. This might've been during the Comic-Con Dump-A-Thon.
Penny: You have names for our breakups?
Raj: Well, they would really blur together if we didn't.
Sheldon: The Comic-Con breakup's easy to remember because Leonard was the saddest Pikachu.
Amy: Right, and he wiped his nose on your cape, and then you were the saddest Darth Vader.

Amy: I'm all for promoting women in science, but I don't really want to be on Wil's show.
Sheldon: Is it because kids may be there, and they're known carriers of head lice? I get that.
Amy: Sure, that's the reason.
Sheldon: Wait a minute. You're always bragging that lice aren't attracted to you because your scalp is so oily. That was on your dating profile.

Sheldon: I call this meeting of the Council of Sheldons to order. Let's take roll. Science Sheldon?
Science Sheldon: Present.
Sheldon: Texas Sheldon?
Texas Sheldon: Howdy.
Sheldon: Fanboy Sheldon?
Fanboy Sheldon: Greetings.
Sheldon: Germaphobe Sheldon?
Germaphobe Sheldon: Say it, don't spray it.
Humorous Sheldon: Where's Jock Sheldon?
Sheldon: Not the time, Humorous Sheldon!
