[Knock... knock... knock]

Sheldon Cooper:
Amy?

[Knock... knock... knock]

Sheldon Cooper:
Amy?

Amy Farrah Fowler:
What?

Sheldon Cooper:
I've... never knocked on my own door before. That was a wild ride.

Amy Farrah Fowler:
You don't have to come in here and cheer me up.

Sheldon Cooper:
Yeah, w- Thank you. But you could tell everyone else that, because they sure think otherwise.

Amy Farrah Fowler:
I'll tell you what they think. They think our relationship is a joke.

Sheldon Cooper:
Well, I don't think our relationship is a joke. I think a horse goes into a bar. Bartender says, "Why the long face?" That's a joke. It's a good one, too, because a horse has a long face.
