Elliot: Ooh, you know I love to tackle clutter. We'll do it!
Mary: Oh, thank you.

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.
