When Harry Met Sally...1989

Sally:
You know, I am so glad I never got involved with you. I just would have ended up being some woman you had to get up out of bed and leave at three o'clock in the morning and go clean your andirons. And you don't even have a fireplace.

Harry:
Why are you getting so upset about this?

Sally:
You are a human affront to all women. And I am a woman.

Harry:
I think they have an OK time.

Sally:
How do you know?

Harry:
What do you mean how do I know? I know.

Sally:
Because they...

Harry:
Yes, because they...

Sally:
And how do you know that they really...

Harry:
What are you saying, that they fake orgasm?

Sally:
It's possible.

Harry:
Get outta here!

Sally:
Why? Most women at one time or another have faked it.

Harry:
Well they haven't faked it with me.

Sally:
How do you know?

Harry:
Because I know.

Sally:
Oh, right, that's right, I forgot, you're a man.

Harry:
What is that supposed to mean?

Sally:
Nothing. It's just that all men are sure it never happened to them and that most women at one time or another have done it so you do the math.

Harry:
You don't think that I could tell the difference?

Sally:
No.

Harry:
Get outta here.

[Sally begins to fake an orgasm]

Harry:
Are you OK?

[Sally continues very audibly, attracting the attention of nearly every customer in the cafe. Afterwards, she returns to eating her dessert]

Older Woman Customer:
[to waiter] I'll have what she's having. Note: the bolded line is ranked #33 in the American Film Institute's list of the top 100 movie quotations in American cinema.
