George Cooper Sr.: Let me tell you about my day. I got yelled at by the principal for benching a linebacker who's flunking English. Then I got yelled at even more by the kid's parents. Then I had to break up a fight in the locker room. Got elbowed in the neck.

Sheldon Cooper: That's a rough day.

George Cooper Sr.: That was all before 10:00 a.m. So I get what you're going through. But you'll notice, I didn't come home and take it out on you.

Sheldon Cooper: No, you didn't.

George Cooper Sr.: I want you to get back in there, apologize to everyone, and finish your dinner.

Sheldon Cooper: Yes, sir.

Sheldon Cooper (narration): My father's wisdom touched me deeply. Which is why, to this day, no matter what I'm going through, I am never irritating or abusive to any of my friends or loved ones. Ask them. They'll tell you.
