Sheldon: Thanks, Dad. We're gonna give them hell.

Leonard: I have something that might help. It's-it's a recording of the only person whose opinion Sheldon actually respects.
Amy: Hawking? Feynman?
Leonard: No, himself.

Leonard: It's a pep talk he made when he was a kid. He gave it to me years ago and told me to save it for a real emergency.
Penny: What? You didn't break it out when he declared his room a sovereign nation and waged a trade war against us?
Leonard: His major export is talking. I didn't want that anyway.

Amy: Hey.
Sheldon: Hello.
Amy: "Fine with flags"?
Sheldon: Yes, flags, up there flapping around on poles. If you think about it, they're just the strippers of the emblem world.

Amy: Okay, all hooked up. Here we go. Oh, look how cute you were!
Sheldon: Amy, please, of course I was cute. Look how I turned out.

Beverly Hofstadter: Yes?
Leonard: Hello, Mother.
Penny: Hey, Beverly.
Beverly Hofstadter: Hello, Leonard. Hello, Penny. To what do I owe this call?
Leonard: I need your professional advice.
Beverly Hofstadter: Well, I'd love to help you out, dear, but I'm very busy at the moment. Perhaps we can schedule a time next week.
Penny: It's about Sheldon.
Beverly Hofstadter: Oh, well, I-I suppose I can spare a minute or two.
Leonard: Wh-Why did you just say you're too busy, but-
Beverly Hofstadter: Leonard, please, not everything is about you.

Sheldon: Why are you watching that?
Amy: I'm just looking to see if there's anything left of your speech.
Sheldon: It's not important. I remember everything I said.
Amy: And?
Sheldon: It was good, it just would've meant more coming from me.

George Sr.: [on video] I know we're down, by a lot. And if I'm being honest with you, we're probably not gonna win this one. In fact, we're definitely not gonna win this one.
Amy: Do you want me to turn it off? [Sheldon shakes his head]
George Sr.: [on video] But we're not gonna quit, either. And if we do lose, you need to know that doesn't make you losers. You learn as much about who you are and what you're made of from failing as you do from success. Maybe more. So you can spend the next half feeling sorry for yourselves, or you can get out there and give them hell.
Georgie: [on video] Yeah! Let's give them hell!
George Sr.: [on video] Oh, watch your mouth, your mom might-

Amy: Oh, so now you're reevaluating every opinion you've ever had?
Sheldon: Yes. I am following the example of 17th century philosopher René Descartes.
He subjected all his beliefs to radical doubt so that he could build a bedrock belief and build his cognitive life back up on firm principles. [eating asparagus] Ugh! Still yucky, still yucky.

Amy: Sheldon, I know you're upset about the paper, okay. I'm upset, too.
Sheldon: I mean, I was so sure we were right. Every fiber of my being felt like this was it. This was the one. How can I trust my instincts anymore?
Amy: Well, just because our theory was wrong, that doesn't mean you're wrong about everything.
Sheldon: Doesn't it? I've always thought I hated jazz, maybe I was wrong. Maybe it's great to hear all the notes at once. [music plays] I'm trying, I'm really trying!

Amy: Well, I got something that I think might cheer you up. It is the emergency pep talk you made when you were a kid.
Sheldon: Oh, that. I was saving it for the day they stop making Star Wars movies. I don't think that's ever gonna happen.

Young Sheldon: Hello, Sheldon.
Sheldon: Hello, Sheldon.
Young Sheldon: If you're watching this, I assume something bad has happened. Something unfortunate and unforeseen. Something that's making you question everything.
Sheldon: I'm so smart.

Young Sheldon: Now just to make sure it's really you watching this and not an imposter, what am I thinking of? On the count of three. One, two, three.
Sheldon: Robot monkey butler.
Young Sheldon: Robot monkey butler. Okay, good.

Howard: Why is it all in the living room?
Bernadette: Because I think The Great Howdini deserves to be a member of the Magic Castle.
Howard: That's sweet, but I'm not that guy anymore. I've outgrown it.
Bernadette: [holding up Howard's costume pants in front of him] Have you?

Beverly Hofstadter: Penny, go on.
Penny: Well, ever since his paper got disproven, he's been a wreck. He's been sad and and angry. He just seems kind of broken.
Beverly Hofstadter: Well, it sounds like he may be grieving.
Penny: Really? Over a theory?
Beverly Hofstadter: Of course. You can grieve over any emotional loss. The more you care about something, the greater the trauma of losing it.
Leonard: Oh, boy. He cared about this a lot.
Penny: Yeah. What can we do to help him?
Beverly Hofstadter: Well, grieving is a process. Every culture has its own rituals and traditions to facilitate mourning. The ancient Egyptians had their mummification, the Tibetans had their sky funerals-
Leonard: And when I was little and my dog died, my mom sat me down and very gently told me that she wished the truck had hit my dad instead.
Beverly Hofstadter: I was trying to lighten the mood. Your dog had just died.
