Adult Sheldon: Presenting... "Sheldon Cooper's Top Five Sources of News From My Childhood". Number five: Star Trek Fan Club Magazine.
Sheldon: Mom, DeForest Kelley's favorite episode is "The Empath."
Mary: Good to know.
Adult Sheldon: Number four: the Weather Cube from RadioShack.
Man: [from device] The humidity is 90% with a dew point of 79.5 degrees.
Sheldon: Mom! The dew point is 79.5 degrees.
Mary: [o.s.] Okay.
Adult Sheldon: Number three: The MacNeil/Lehrer NewsHour. Such a great theme song.
Sheldon: [hums] Buh-buh-bum.
Adult Sheldon: Number two: Meemaw after a few beers.
Meemaw: It took a while, but we finally picked a new name for my bowling team: The Ball Busters.
Sheldon: Hey, Mom. Guess what Meemaw named her bowling team? The Ball...
Adult Sheldon: And the number one source of news from my childhood: the bulletin board at the train store. News about trains in a store full of trains. Yummy.
Sheldon: How did this not make The MacNeil/Lehrer NewsHour?

Adult Sheldon: I didn't realize until years later that my father was only asking questions about lightning and thunder to cheer me up. In fact, he would often pretend to be dumb just to make me feel better.

Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George Sr.: Talked to Billy.
Missy: Why would you do that?
George Sr.: No, it was good.
Missy: Stay out of my life.
Adult Sheldon: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

Adult Sheldon: Visiting Tam's house for the first time was an emotional roller coaster.
For example, it's traditional in Vietnamese homes to have gruesome religious iconography near the entrance. I did not like that.
However, it's also customary to not wear shoes around the house for sanitary reasons. I did like that.
Interestingly, one of the main ingredients in Vietnamese cooking is an extremely pungent condiment known as fish sauce. I did not like that.
But before every meal, it's common for everyone to wash their hands and face. I did like that.
Forks are not customary in a Vietnamese household. I did not like that.
And instead of napkins, there was one towel for everyone to share at the table. Seriously, what are they thinking?

Mary: [eating pop corn] Get him, Dalton. Get him.
George Jr.: Mary Cooper, what are you doing?
Mary: Nothing.
George Jr.: Why are you watching Road House?
Mary: Why aren't you at work?
George Jr.: I asked you first, and my question is way more interesting.
Mary: It was just on. I don't even know what that is.
George Jr.: Then how'd you know his name's Dalton?
Mary: I don't have to explain myself to you.
George Jr.: This is a pretty dirty movie.
Mary: How do you know? It is rated R.
George Jr.: For violence, language and sexual content. You should be ashamed of yourself.

Meemaw: Alls I'm saying is people aren't always in the mood.
Sheldon: Well, they should be. I'm happy to learn any fact at any time.
Meemaw: Is that so?
Sheldon: Yes.
Meemaw: Grab my knitting bag.
Sheldon: I don't recommend driving while knitting. Your reflexes aren't what they used to be.
Meemaw: Just look in the bag! Did you know that there are three different kinds of yarn?
Sheldon: I didn't.
Meemaw: You got your animal, like wool. Your plant, like cotton. And your synthetic, like acrylic.
Sheldon: Interesting.
Meemaw: You think so? I'm glad to hear that. Because each one of them has plusses and minuses, and you're about to hear them all in mind-numbing detail.

Sheldon: The train museum's looking for a docent.
Mary: What's a docent?
Sheldon: It's a person in a museum who gives information on the exhibits.
Mary: Do you think they'd let someone your age do that?
Sheldon: Why not? I have a high school diploma.
Mary: True.
Sheldon: I know more about trains than anybody.
Mary: True.
Sheldon: And I have the unique ability to wear people down until I get my way.
Mary: So true.
