Perfect lines. So inspired. So well written, Yet so simple

JERRY: So as you can see, I've got a little problem here.
GEORGE: Well if I'm hearing you correctly. And I think that I do, my advice to you is finish your meal, pay your check, leave here, and never speak this to anyone again.
JERRY: Can't be done, huh?
GEORGE: "The Switch?"
JERRY: "The Switch."
GEORGE: (Shakes head) Can't be done.
JERRY: I wonder.
GEORGE:(Pounds table.) Do you realize in the entire history of western civilization no one has successfully accomplished the Roommate Switch? In the Middle Ages, you could get locked up for even suggesting it.
JERRY: They didn't have roommates in the Middle Ages.
GEORGE: How do you know?
JERRY: Well, for one thing, they didn't have apartments.
GEORGE: Well, I'm sure at some point between the years 800 and 1200, somewhere there were two women living together.
JERRY: The point is I intend to undertake this. And I'll do it with or without you. So if you're scared, if you haven't got the stomach for this, let's get it out right now! And I'll go on my own. If not, you can get on board and we can get to work! Now what's it going to be?
GEORGE: All right, dammit, I'm in.
JERRY: I couldn't do it without you.


JERRY: All right. So I tell Sandy that I want to have a ménage à trois with her and her roommate.

GEORGE: That's right.
JERRY: And you believe this course of action will have a two-pronged effect. Firstly, the very mention of the idea will cause Sandy to recoil in disgust, whereupon she will insist that I remove myself from the premises.
GEORGE: Keep going.
JERRY: At this point, it is inevitable that she will seek out the roommate to apprise her of this abhorrent turn of events.
GEORGE: Continue.
JERRY: The roommate will then offer her friend the requisite sympathy even as part of her cannot help but feel somewhat flattered by her inclusion in the unusual request.
{George takes over.}
GEORGE: A few days go by and a call is placed at a time when Sandy is known to be busy at work. Once the initial awkwardness is relieved with a little playful humor, which she (Laura) of course cannot resist, an invitation to a friendly dinner is proffered.
JERRY: Huh. Well, it all sounds pretty good. There's only one flaw in it: They're roommates. She'd have to go out with me behind Sandy's back. She's not gonna do that.
{Another pregnant pause. George?}
GEORGE: You disappoint me, my friend. Sandy wants nothing to do with you. She tells Laura, "If you want to waste your time with that pervert, that's your problem."
{Final pause. Jerry?}
JERRY: It's a perfect plan. So inspired. So devious. Yet so simple.
GEORGE: {George, finger in the peanut butter jar}: This is what I do.
