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-

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.
