Sheldon: I have the opportunity to participate in a prestigious summer program at the University of Heidelberg.
Mary: Sheldon, I don't...
Sheldon: I know that you're probably gonna say that I'm too young or it's too far away, but please just hear me out.
George: He did bring us snacks.
Mary: Beer is not a snack.

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

Sheldon: There's going to be a lecture on carbon dating at the Natural Science Museum on Saturday. Who would like to take me?
George: You know what? I'd be happy to.
Meemaw: What happened to helping me at my yard sale?
George: Ooh, is that this Saturday? I'm sorry. I'm taking him to a lecture on, uh what is it? Carbonation?
Sheldon: Carbon dating. A method of determining the age of artifacts and fossils.
George: Hey, we could use that to figure out how old your grandma is.
Sheldon: That won't work. You can't carbon-date something that's alive.
George: Well, then, we'll just chop her down and count the rings.
Meemaw: Oh, George, did my "lump of clay" remark strike a nerve?
George: A little.

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.

Mary: Well, we're gonna have to talk to Dr. Sturgis before we make any decisions.
George: We're- We're not making any promises.
Mary: Mm-hmm.
George: This is not a yes.
Sheldon: But it's also not a nein, which German for "no", as opposed to the number nine, which is neun.

Sheldon: I brought you some snacks. For Mom, a Bavarian-style pretzel. And for Dad, four Lone Star beers poured into a pitcher to approximate a stein.
George: What do you want?
Sheldon: For starters, a danke wouldn't kill you.
Mary: A what?
Sheldon: It's "thank you" in German. Uh, so, if you were thinking of thanking, then you'd be denken of danken. You're awfully quiet. I assume you're denken.
Mary: W-Where are you going with all this?
Sheldon: If I play my cards right, Germany.

Mary: Sheldon... [sighs] aren't there programs that are closer?
Sheldon: Yes, but I missed my chance to get into any of them. In fact, Dr. Sturgis had to call in a big favor to get this opportunity.
George: Well, that's nice of him, but maybe he should have talked to us first?
Sheldon: Oh, he suggested that.
Mary: And?
Sheldon: I nixed it.
Mary: You nixed it?
Sheldon: From the German nichts. The language lends itself to negativity.
