George Sr.: Since when do we get MTV?
George Jr.: Since I got cable.
George Sr.: What do you mean, you got cable?
George Jr.: I called up the cable company and I said, "Hello, I'd like cable," and they put in cable.
George Sr.: I'm not paying for that.
George Jr.: Keep your shirt on. I paid for it.
George Sr.: Is that so?
George Jr.: Yeah, with money I saved from my job.
George Sr.: Well, okay. So do we get any of those movie channels?
George Jr.: Dad, I'm trying to watch the news.

George Jr.: What are you doing?
George Sr.: Separating the whites from the colors.
George Jr.: Whoa, that's racist.

George Jr.: I think the saddest part about it is just how sad it is.

George Jr.: So, Vietnam, like in Rambo.
Tam: Yes.
George Jr.: That's a cool movie.
Tam: Yes.
George Jr.: Are you in it?
Tam: No.

Adult Sheldon: A primary feature of quarks is that they're always bonded together, but in that moment, I felt like a neutrino, destined to be alone forever.
[Montage of young Leonard, Penny, Raj, Howard, Bernadette and Amy at that moment]
Adult Sheldon: Thankfully, I was wrong.

Meemaw: John?
Dr. John Sturgis: Hello.
Meemaw: What- What're you doing?
Dr. John Sturgis: I was doing tai chi and then I realized that I was continually being bombarded by subatomic particles and it behooves me, perhaps, to pay slightly closer attention to them. Maybe "chi" is the ancient Chinese word for the subatomic universe.
Meemaw: You're scaring me, John.
Dr. John Sturgis: Well, there's nothing to be scared of. Tomorrow, somebody will win the Nobel Prize about these particles not me. But I'm experiencing them firsthand [LAUGHS] which could be better.
Meemaw: Why don't you come down and experience them on the floor?
Dr. John Sturgis: I think I just felt a neutrino. [LAUGHING] You know, neutrinos are interesting. They never bond with anything, they're always alone. I think that one went right through my pants.
Meemaw: All right, why don't we go downstairs, and I'll fix us both a nice cup of hot tea and you can tell me all about it. Please?
Dr. John Sturgis: Okay. It was my dream to win the Nobel, and I'm not going to. I bet Sheldon will.
Meemaw: That'll be something.
Dr. John Sturgis: Yeah.

George Jr.: A bill? Really?
George Sr.: Room and board, buddy.
George Jr.: $50 a month for food?
George Sr.: The way you eat, I should've gone $50 a week.
George Jr.: Laundry services?
George Sr.: Your poor mother has to touch your underwear.
George Jr.: What's the $10 a month "peema" charge?
George Sr.: Oh, P-I-M-A, that's a "Pain in My Ass" tax. My way of getting compensated for you taking years off my life.
