All: Trick or treat.
Judy: Aren't y'all precious. And you look like a little Carl Sagan.
Adult Sheldon: Vindication, the sweetest candy of all.

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?

Tam: You see a large red button. What do you do?
Billy Sparks: I press it.
Tam: The floor opens up and you plunge into a 60-foot pit.
Billy Sparks: I fly out. Up, up, and away!
Sheldon: Again, you're not Superman in this game; you're Superman for Halloween.
Tam: Which isn't till next week.
Billy Sparks: So I'm in a pit.
Tam: You're in a pit.
Billy Sparks: Then I blast my way out with my super breath! [BLOWING]
Sheldon: Just let him do it.

Mary: I can't believe this.
George Sr.: No good?
Mary: It's awful. It makes sin seem like a good thing.
George Sr.: Well, that's the problem, isn't it? I mean, if sin didn't seem like a good thing, nobody would do it.
Mary: George, please, I'm in no mood.
George Sr.: Hey. Wrath. That's one of the seven sins, right?
Mary: Pastor Jeff gave me this project because he knew I'd be best at it. Now Gene Lundy is taking over.
George Sr.: Oh, look, pride. And envy. Don't stop. Four sins to go. I'm guessing lust ain't happening tonight.

George Jr.: Sheldon.
Sheldon: Oh. Hi, Georgie.
George Jr.: Why was Veronica Duncan hugging you?
Sheldon: I'm tutoring her in trigonometry.
George Jr.: And that gets you hugs?
Sheldon: Thanks to me, she got her first C-minus. Just between us, she's a little slow.
George Jr.: That's not what I heard.
Sheldon: What did you hear? Is she secretly clever? Because if she is, I completely missed it.
