Arthur Jeffries:
Can I ask you a question?

Leonard Hofstadter:
Yeah, sure.

Arthur Jeffries:
Why do you put up with Sheldon?

Leonard Hofstadter:
Oh, um, you know. Because we're friends.

Arthur Jeffries:
Why?

Leonard Hofstadter:
Wow. You ask really hard questions. Look, I know he can be aggravating, but you have to remember he's not doing it on purpose. It's just how he is. Oh, but he's also loyal, and trustworthy and we have fun together.

Arthur Jeffries:
You know, you're describing a dog.

Leonard Hofstadter:
He did bite me once. But in his defense I came up behind him while he was eating.

Arthur Jeffries:
They hate that.

Leonard Hofstadter:
You, know what. Sheldon is the smartest person I've ever met. He's a little broke and he needs me. I guess I need him too.

Arthur Jeffries:
Why's that?

Leonard Hofstadter:
You will not let this go.
