Dr. John Sturgis: Did you know that when Albert Einstein was a little boy, his parents worried there was something wrong with him?
Missy: Because he couldn't comb his hair?
Dr. John Sturgis: No, that was a choice he made later in life. When he was young, he wanted nothing to do with other children, and would often have extreme temper tantrums.
Missy: He sounds like you.
Sheldon: I know. Isn't it great?

Dr. Edward Pilson: Okay, Sheldon, this first battery of tests measures basic problem-solving abilities.
Sheldon: Is the Kaufman test or the Wechsler Intelligence Scale?
Dr. Edward Pilson: Are you familiar with those?
Sheldon: It's embarrassing, but I enjoy a little light reading in the bathroom.

Sheldon: Kudos on the question "Which train gets to St. Louis first?"

Sheldon: Hot dog, syllogisms. "If all squares are parallelograms, and all squares are rectangles, then some parallelograms are rectangles." Who was this test made for, children?

Mary: Did you have fun?
Sheldon: I got to take a test on a Saturday, heck yeah!

Missy: What you watching?
George Jr.: Soul Train.
Sheldon: I like trains.
George Jr.: It's not that kind of train, dummy.
Sheldon: Well that seems like false advertising.

Dr. Edward Pilson: Sheldon, what do you think is happening in this picture?
Sheldon: Easy. There are four chimpanzees in a living room.
Dr. Edward Pilson: Okay, but what can you tell me about them?
Sheldon: They're not behaving like chimpanzees.
Dr. Edward Pilson: Anything else?
Sheldon: Chimpanzees don't drink tea.
Dr. Edward Pilson: Is that it?
Sheldon: Well, I suppose it might be coffee, but they don't drink that either.
Dr. Edward Pilson: Anything interesting about their body language?
Sheldon: No.

Sheldon: A woman in a doorway.
Dr. Edward Pilson: Anything else?
Sheldon: She's holding her head with her hand.
Dr. Edward Pilson: And what do you think that means?
Sheldon: Um, Wouldn't you rather ask me about trains going to St. Louis?

Sheldon: A lion sitting in a chair, holding a pipe.
Dr. Edward Pilson: Good. But what do you think is on his mind?
Sheldon: How should I know? Maybe he's wondering why he's posing for a silly picture instead of eating a gazelle.

Dr. Edward Pilson: Anything else?
Sheldon: What exactly are we doing here? I thought the purpose of this study was to find out how smart I am.
Dr. Edward Pilson: That's what we're doing, but there are different kinds of intelligence.
Sheldon: Poppycock! There's only one kind of intelligence.

Sheldon: "If you were not covered by a retirement plan, but your spouse was, see the worksheet on page 14." Try and stop me.

Mary: I've been buying groceries for the church food drive. I think that's it.
Sheldon: Ooh, I bet I could write that off, including the gas it took to drive to the grocery store and then to the church.
George Sr.: With all that driving, maybe she can count her car as a home office.
Sheldon: Sounds aggressive, but I like how you're thinking.

Sheldon: Dad, banking question.
George Sr.: What's that, buddy?
Sheldon: I noticed there's a check missing. I have a copy of check 128 and a copy of check 130, but 129 isn't there.
George Sr.: Oh, yeah, don't worry about it.
Sheldon: But I enjoy worrying; I find it very relaxing.
George Sr.: 'course you do.

Sheldon: I balanced the rest of the account, and it appears to be a check for $300.
George Sr.: All right, well, let's just put it down for $300 for miscellaneous.
Sheldon: I've never labeled anything miscellaneous in my life.

George Sr.: What do you say we keep this quiet?
Sheldon: You mean like a secret?
George Sr.: No, no, just, you know, something between you and me.
Sheldon: What about Mom?
George Sr.: Mom is on a need-to-know basis.
Sheldon: What if Mom needs to know?
George Sr.: Okay, it's a secret. Just trust me. It is better for everyone if she doesn't know about this.
Sheldon: But I'm not good at keeping secrets.
George Sr.: It's not hard. Just keep your mouth shut.
Sheldon: But I'm not good at keeping my mouth shut.

Mary: Sweet dreams. Love you.
Sheldon: Love you, too, 'cause you're my mom. [LAUGHS NERVOUSLY]

Missy: You're so weird.
Sheldon: More than usual?
Missy: No, I guess not.
Sheldon: Perfect.

Adult Sheldon: To avoid looking suspicious, I tried to interact with my mom as little as possible. Thankfully, it's rude to speak with your mouth full.
Mary: You look tired, baby. Sleep okay?
Sheldon: [shoveling food into his mouth] Mm-hmm.
Mary: So how big a tax refund you think we're gonna get?
Sheldon: [pointing at his mouth] Mm.

Adult Sheldon: There was only so much food I could eat, so I started avoiding my mother whenever possible.
George Sr.: [OPENING A CUPBOARD AND FINDING SHELDON] What are you doing in there?
Sheldon: [WHISPERING] Keeping your secret.
George Sr.: You got to pull it together.
Sheldon: This is me pulling it together.
George Sr.: Pull harder.

Adult Sheldon: Avoiding my mother in our own house was proving to be difficult, so it was time to get creative.
Sheldon: Hello. I'd like to book a room in your hotel. I'd be arriving tonight. No, it's just me. Ooh, a queen bed, that sounds fancy. And how much would this room cost? Wow. Is that per month? Per day? By any chance, do you have a children's rate?
