Too bad you never saw the movie. Here's the script from that scene, but it doesn't do it justice.
Harry: Hey I don't feel great about this but I don't hear anyone complaining.
Sally: Of course not you're out of the door too fast.
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: Ooo...Oh...Ooo...
Harry: Are you OK?
Sally: Oh...Oh god...Ooo Oh God...Oh...Oh...Oh...Oh God...Oh yeah right there
Oh! Oh...Yes Yes Yes Yes Yes Yes...Oh...Oh...Yes Yes Yes....Oh...Yes Yes Yes
Yes Yes Yes...Oh...Oh... Oh... Oh God Oh... Oh... Huh...
(Sally finishes, looks at Harry and smiles. Harry looks back, looking a
little uneasy)
Lady from another table: I'll have what she's having.
