Mary: Um, I have Sunday's bulletin for your approval. And I wanted to ask about ordering the palms for Palm Sunday. I know it's early, but as you remember last year, we waited too long and First United Methodist snatched up all the perky ones.

Sheldon: Regardless, I'm not interested in making any more friends.
Mary: Oh, I don't think that's how you really feel.
Sheldon: It is. From now on, it's a hermit's life for me.
Mary: I bet, when you grow up, you will be surrounded by lots of smart, wonderful friends.
Sheldon: I can't see that happening.

Sheldon: Mom, when should I be expecting my testicles?
Woman: [turns around] What is wrong with him?
Mary: Nothing is wrong with him. Now turn around before I knock your lights out.
Sheldon: Hello.

Mary: Sheldon Lee Cooper, if you don't finish that pork chop, I swear I will chew it up and spit it in your mouth like a mama bird.
Missy: Do it, Mom. Do it.

Adult Sheldon: Dr. Sturgis was a wise man. It was a learning opportunity. And when the day comes that I'm wrong, I fully plan to admit it.

Ms. Hutchins: Sheldon, why aren't you in second period?
Sheldon: I'm working on this math problem.
Ms. Hutchins: I think you might be the first person in history who's ever cut class to do math.
Sheldon: The irony wasn't lost on me.

Sheldon: Thank you for asking. I appreciate it. And how are you doing?
Ms. Hutchins: Since when are you interested?
Sheldon: My father told me I should be kind to old people.
Ms. Hutchins: How old do you think I am?
Sheldon: My father also told me if a woman ever asks you that, it's a trap.
Ms. Hutchins: Smart man.
Sheldon: But I'll say 53.
