Leonard Hofstadter:
[singing] I'm sorry Alex hit on me, hit on me, hit on me. Sorry Alex hit on me, I'd no idea I'm cute.

Penny:
Oh, damn it, you are.

Leonard Hofstadter:
Please forgive me. I should have told you about Alex.

Penny:
I don't care about Alex. Fine, I care. Okay, I hate that b*tch. But what really hurt is that you liked it so much. I mean, do I need to be worried?

Leonard Hofstadter:
Of course not. No. Why?

Penny:
Because, she is pretty and smart, and when you talk about work, she doesn't have to go home and look up words in the dictionary to understand what you said.

Leonard Hofstadter:
You do that?

Penny:
No.

Leonard Hofstadter:
Hang on. Are you feeling insecure? Because that's my thing, and if you take it away, I don't know what I'm bringing to this relationship.

Penny:
Yes, Leonard, I am insecure. Happy?

Leonard Hofstadter:
No, not happy.

Penny:
Why are you smiling?

Leonard Hofstadter:
I'm sorry. I just never think of you having feelings like that.

Penny:
Well, I do.
