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: And Sheldon's fine. You know what he's like. If someone took him, I'm sure they'll bring him right back.

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.

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.

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: "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.

Sheldon: If you're going to the grocery store, you should get more tinfoil.
George: [sighs] You're not making a hat, are you?
Sheldon: No. I need it to black out my windows. It's 10:00 p.m. in Heidelberg. Gute Nacht.
George: [exhales] Tinfoil.
