Leonard Hofstadter:
Do you think I'm overdressed?

Sheldon Cooper:
Depends on the activity. For a prostate exam, yes. To play in Vegas, I'd add sequins.

Leonard Hofstadter:
I'm going to the movies with Penny. I don't want her to think that I think it's a date.

Sheldon Cooper:
Do you think it's a date?

Leonard Hofstadter:
No. But she might think that I think it's a date even though I don't.

Sheldon Cooper:
Or you might think she thinks you think it's a date even though she doesn't.

Leonard Hofstadter:
Are you overthinking this?

Sheldon Cooper:
Not at all.

Leonard Hofstadter:
You're right. I'm fine. I'm wearing this.

Sheldon Cooper:
Really? A blazer? All right.
