Sheldon: Unbelievable. It's either cartoons or men in their underwear banging their heads together.
Ricky: You complain a lot.
Sheldon: Excuse me?
Ricky: Seriously, dude, you need to relax.
Sheldon: How can I relax? I'm being held captive in a bacterial playground.

Mary: Sheldon, who are you talking to?
Sheldon: Dorothy Fitzpatrick.
Mary: Who's Dorothy Fitzpatrick? Is she a new buddy from school?
Sheldon: She's the loan officer at The First National Bank of Medford.
Mary: Why are you talking to her?
Sheldon: Mom, can this wait? I'm trying to negotiate favorable terms. Hello, Dorothy? [Mary hangs up]

Sheldon: Per the student dress and grooming code, this boy's hair is too long. This boy's wearing sports attire outside a designated area. And this girl's blouse is diaphanous, which means I can see her brassiere.

Missy: What's it like to not believe in God?
Sheldon: It's great. Big fan.
Missy: Are you ever afraid you're wrong?
Sheldon: About religion? Never. About other things? Also never.

George: You're not gonna make it in this school if you keep ratting people out.
Sheldon: But they were breaking the grooming codes and the dress codes. I saw one boy with a t-shirt that said... [leans in and whispers] "Bite me".
George: Yeah, that's terrible. [Sheldon nods]

Sheldon: And this program will allow us to track our family finances, create a budget, and prepare tax documents.
George: That's impressive.
Sheldon: Would you like to know how much money you spend on beer annually?
George: No.
Mary: I would.
Sheldon: $936.
Mary: George!
Sheldon: If you switched to Hawaiian Punch, we could live in a bigger house.

Sheldon: This isn't the Hello Kitty store.
Paige: No. It's Hot Topic.
Sheldon: What's the topic, devil worship?
Missy: Hey, did you know there's a bow tie section in the back?
Sheldon: Why would they hide that in the back? [walks to the back]

Sheldon: What is happening to our family?
Missy: I know. Georgie and Meemaw in jail.
Sheldon: Mom getting kicked out of the church.
Missy: Georgie having a baby out of wedlock. You know what this means, don't you?
Sheldon: What?
Missy: We really are white trash.
Sheldon: Speak for yourself. I'm in college on a full ride. But I wish y'all luck.

Sheldon: Good morning, everyone. Niblingo.
Mandy: I'm sorry, what?
Sheldon: It's an honorific I came up with to describe a woman who's carrying my future niece or nephew but is not related to me by law.
Missy: You remember Sheldon.
Mandy: I do.
Missy: [nods] Yeah.

Sheldon: No one will even listen to my ideas. I'm being discriminated against because I'm too young.
Dr. John Sturgis: I'm sorry to hear that.
Sheldon: I can't wait till I'm your age and people treat me with respect and reverence.
Dr. John Sturgis: Sometimes older people get discriminated against, too.
Sheldon: For what? Getting smaller and cuter year after year? Look at you.

Sheldon: You've been through this before. How long does it take?
Brenda Sparks: Depends. With Billy, it was days.
Sheldon: Well, he always has been a tad slow.

Sheldon: Professor Salzman, I just wanted to let you know that I studied up and am now well-versed in the Calabi-Yau manifold.
Professor Salzman: Okay.
Sheldon: It was never part of the curriculum at East Texas Tech.
Professor Salzman: East Texas Tech? Sounds charming.
Sheldon: It's actually quite humid. Regardless, I'm ready to reassert myself as class leader.
Professor Salzman: Your classmates are from some of the most elite universities in the world. There is no East MIT.
Sheldon: Well, I would have gone to a better school, but I was 11, which you have to admit is pretty impressive.
Professor Salzman: Sheldon, at some point we ask of the piano-playing dog not, "Are you a dog?" but, "Are you any good at playing the piano?"
Sheldon: Excuse me?

George: Studying for a test?
Sheldon: Studying to take the bar exam. Meemaw's going to need a smart lawyer. By the time we find one, I could just learn how to do it.
George: Seriously?
Sheldon: Common law was invented by a bunch of English farmers in the Middle Ages. I think I can hack it.

Sheldon: I'm enjoying this, but I'm having trouble with the onomatopoeia.
Tam: The what?
Sheldon: The onomatopoeia. Words that imitate sounds. "Kthoom" "Snikt" "Bamf" Writers shouldn't make up words.
Tam: Somebody made up "onomatopoeia".
Sheldon: You challenge me. I like that.

Georgie: Tell me, Sheldon.
Sheldon: It occurred to me that a good way to generate a positive cash flow would be to curate popular songs and make them available in a digital form. Possibly on a small device that could also be used as a phone or even a camera.
Georgie: Right. [mocking] A phone, camera, music machine. Get out of here.
