George: Well, you got Germany coming up. Makes sense to be a little nervous.
Sheldon: That does make sense.
George: Yeah. Remember how scared you got when we flew to Pasadena? [chuckles softly] But we got through it. Together.
Sheldon: We did.
George: Germany's way further than that. Your mom's never been on a flight that long before. I have. When I was in the Army. Fighting for our country.
Sheldon: Weren't you in the motor pool?
George: I'm just saying, if your mom gets nervous, you might be the one calming her down.
Sheldon: But that's what she does for me.
George: Well, I'm sure she'll do her best. But if she can't, there's lots of strangers on the plane. You can hold one of their hands.

Mary: So he's really good to graduate?
Principal Petersen: He sure is. I got to tell ya, usually when kids leave school after two years, it's not for college. It's for prison or pregnancy.
George: Well, between Georgie and Missy, we may hit the trifecta.
Mary: George!
George: Well, I'm not rooting for it. It's just a thing that could happen.

Georgie: You know what else is nice?
George: Hmm?
Georgie: I get to learn from all your parenting mistakes.
George: I'm starting to think letting you live this long was one of 'em.
Georgie: Like that. I'd never say something so awful to my kid. [George scoffs] Thanks, big guy.

Georgie: A bill? Really?
George: Room and board, buddy.
Georgie: $50 a month for food?
George: The way you eat, I should've gone $50 a week.
Georgie: Laundry services?
George: Your poor mother has to touch your underwear.
Georgie: What's the $10 a month "peema" charge?
George: 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.

Dr. Linkletter: This will allow us to calculate the speed of sound in the liquid using the standard elements of the Einstein field equations. The answer is only correct, of course, if the density changes slowly. And to begin, we use the standard equations of thermal physics to simplify the answer... [sniffing] Wh-Wha-What am I smelling?
Sheldon: Oh, that might be my sauerkraut and knockwurst.
Ben: [raises hand] It is.
Dr. Linkletter: Why are you eating sauerkraut in my classroom?
Sheldon: I'm acclimating my body to a Germanic meat-based diet.
Dr. Linkletter: At 11:00 a.m.?
Sheldon: It's dinnertime in Heidelberg.
Dr. Linkletter: We're not in Heidelberg.
Sheldon: But I will be over the summer, so I'm trying to adjust my internal clock to the local time so I can hit the ground running mitout jet lag.
Dr. Linkletter: I got to get back to my lecture, if that doesn't interfere with your meal.
Sheldon: Oh, dinner and a show, I love it. Although... would you be a lamb and open this jar of mustard for me?
Dr. Linkletter: Here are two words you don't often hear... poor Germany.

George: You know, you seem pretty stressed out... Maybe it'd be easier if I go to Germany.
Mary: You got to be kidding.
George: Well, it might make more sense. I got the summer off. And, come on, beer and sausage? I've been training for that my whole life.

George: "Chicken boo-eh-lon"? What does that even mean?
Mary: Bouillon. It's the tiny cubes that turn into soup.
George: So, the soup aisle?
Mary: There you go.
