Sheldon: [on the phone] Hello, Dr. Bowers, it's Sheldon Cooper. I need you to administer more anesthesia to me. No, I don't have a dental problem. I need to reenter a trancelike state so I can communicate with Thoth, the god of knowledge. I would argue that the greatest discovery in physics is worth losing your dental license. Well, it's not my fault you let them publish your home phone number.

Sheldon: If I don't go to college, what am I supposed to do? Spend all my days in high school? How sad is that?
Ms. Hutchins: Pretty sad.
Sheldon: You always did get me.
Ms. Hutchins: Sounds like you're feeling misunderstood.
Sheldon: I am... by Dr. Sturgis, my mother, and possibly the entire Vietnamese culture.
Ms. Hutchins: Do you understand that I'm in a little bit of pain right now?
Sheldon: Oh, I'm sorry. I should be exhibiting compassion. Aw. Wait, I can do better. Aw.
Ms. Hutchins: Nailed it.

Sheldon: Well, that's what I heard. And if Hawking doesn't let it stop him, then I can't let this cast stop me.
Missy: Great. Go back to sleep.
Sheldon: I will, and I'll do it all by myself. [sings] Soft kitty, warm kitty
Missy: Oh, my God.
Sheldon: Little ball of fur Happy kitty, sleepy kitty, purr Purr, purr.

Sheldon: Why are they all singing?
Meemaw: Because it's a musical.
Sheldon: But why can't they just say it?
Meemaw: Well, that wouldn't be very musical, would it?
Sheldon: And where is the music coming from?
Missy: You're thinking about it too much.
Sheldon: And how do they all know the same dance?
Missy: Come on!
Meemaw: Moon pie!

[title: Sci-Fi Club:]
Sheldon: So, what kind of activities does the Science Fiction Club engage in?
Greg: Well, this Friday we're having a screening of Star Wars on laser disc.
Sheldon: I thought this was the Science Fiction Club.
Greg: It is.
Sheldon: Star Wars is science fantasy. The Force is basically magic. At that point, you might as well be watching The Hobbit.
Greg: That's next week.
Sheldon: This is madness.

Dr. John Sturgis: Here we go.
Adult Sheldon: For many kids, Christmas morning was the most exciting day of the year. That's only because most kids don't know the joy of getting their college midterms back. It also didn't hurt that Dr. Sturgis looked like an elf.
Dr. John Sturgis: Nice work, Sheldon. Now, you'll notice that your grades are lower than expected. That's because Sheldon did so well, he broke the curve, turning your A's and B's into B's and C's.
Sheldon: They don't seem happy about it. Maybe you can give them candy.

Mary: How about you all come work at our house?
Sam: I guess if that's our only option.
Mary: It'll be fun. I'll make food. You can even bring your laundry.
Keith: That actually would be great.
Sheldon: Now this man's soiled underpants will be in my kitchen. Thank you.

Sheldon: Did he apologize?
Mary: No. He is very upset with you.
Sheldon: Well, I'm upset with him.
Mary: That doesn't excuse you from trying to get him in trouble by calling Dr. Linkletter.
Sheldon: Who else was I supposed to tattle to? I doubt his mother's still alive.

Dr. Linkletter: Just a warning: today's lecture is rather advanced.
Sheldon: Don't worry. If you get confused, I'll be right here in the front row.

Ms. Hutchins: Hi, Sheldon, what can I do for you?
Sheldon: Do you have any books or videos on the Lamaze technique?
Ms. Hutchins: Uh-oh. Georgie get that girl pregnant?
Sheldon: It's for me. I need to have a tooth pulled, and I'd like to do it without putting my brain on drugs.
Ms. Hutchins: Okay.
Sheldon: I've seen that commercial with the egg in the frying pan. Very effective.

Sheldon: Same room. Different teacher. Same night. Different time. This is a real roller coaster.
Meemaw: Yeah, it's wild.

Sheldon: I may not look it, but I'm the future of physics, so just move on.

Meemaw: Hey. Good news. Your dad's doing okay and should be home in a couple of days.
Missy: Thank God.
Sheldon: Thank modern medicine.

Dr. John Sturgis: In my dreams, I'm usually running for my life from a giant praying mantis.
Sheldon: That's the insect where the female eats the male after mating?
Dr. John Sturgis: It is.
Sheldon: I think I understand why you're not married.

Sheldon: "And finally, both parties agree the loser will do the activity selected by the winner graciously, without complaint. For the purpose of this agreement, a complaint is defined as any disparaging comment, eye rolls or name calling, including but not limited to: 'dingus, ' 'fartbreath' and 'buttwipe.'"

Keith: How about we work in my dorm tomorrow?
Mary: Um, I don't know if a dormitory is the right environment for someone his age.
Sheldon: If you're worried about the beer-drinking, Dad has thoroughly desensitized me.

Sheldon: Thank you.
Libby: Happy to help.
Sheldon: Is there any chance you'd be available to stand guard at 1:45?
Libby: You have a bathroom schedule?
Sheldon: You don't?

Mary: Calm down. It was just the 4:00 news. I'm sure no one saw it.
Sheldon: I hope a lot of people saw it and Happy Hearth is forced to give our country good bread again.

Mary: All right, I'll make a deal with you.
Sheldon: I'm listening.
Mary: You can go to Houston with your friends, but I want to meet this girl first.
Sheldon: That's very reasonable. Thank you.
Mary: You're welcome.
Sheldon: Now, can you please reach the dryer sheets? I get vertigo on the step stool.

Mary: Mr. Lundy? Come in. What brings you here?
Mr. Lundy: I'm the listing agent on the house next door.
Mary: But I thought you were a teacher and a...
Mr. Lundy: And an actor, yeah, yeah, yeah, yeah, yeah. You've got to get your son out of my open house.
Mary: Why, what's he doin'?
Mr. Lundy: Well...
[flashback montage:]
Sheldon: I noticed there's hair on your coat. Clearly yours is falling out, but do you also have pets?
Sheldon: I detect a hint of garlic. Do you enjoy cooking stinky foods or are you afraid of vampires?
Sheldon: Is there any chance you're just fat?
[present:]
Mary: Oh, dear, I'll go get him.
Mr. Lundy: Thank you. Kind of a dump. But I could sell it.
