Missy: I thought Mom was going.
George: We're exploring our options.
Mary: Well, I've been thinking about it. You've traveled the world. I've never left the country.
George: [scoffs] The Army isn't "traveling the world".
Mary: More than I've done.

Sheldon: Regardless, I'm not interested in making any more friends.
Mary: Oh, I don't think that's how you really feel.
Sheldon: It is. From now on, it's a hermit's life for me.
Mary: I bet, when you grow up, you will be surrounded by lots of smart, wonderful friends.
Sheldon: I can't see that happening.

Sheldon: Mom, when should I be expecting my testicles?
Woman: [turns around] What is wrong with him?
Mary: Nothing is wrong with him. Now turn around before I knock your lights out.
Sheldon: Hello.

Sheldon: And then they laughed at me for not knowing something that they knew. Who does that?
Mary: You do.
Sheldon: Well, this is no time for a teachable moment. Your child is hurting.
Mary: Sorry. [taps Sheldon's shoulder] There, there.
Sheldon: I guess that'll do. Now, how about a hot beverage?

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.

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.
