Shrewdinger's Rat

The stage is dark.

We hear a scurrying sound, followed by a shrill shriek.  Another scurry, followed by some low-level blasphemy and rummaging, then a thud.

The lights rise suddenly on a dingy living room, with a couch, a side table with a lamp.  On the back of the couch is a tie.  In front of the couch is a large cardboard box, open side downwards.  Kneeling on the couch and pressing down on the box is a very agitated and unhappy looking open-shirted bed-headed Joe.

Marie, dressed up to go out, is standing in the door, by the light switch.

Marie   What the hell is going on in here?

Joe       A rat!

Marie   A rat?

Joe       Yes, a rat!

Marie   A rat?

Joe       I said -

Marie   But we’re meant to be going out!

Joe       Well that can wait until we have dealt with the rat.

Marie   I mean, a rat in here?  That's weird.

Joe       It's not just weird, it's in this box.

Marie   Seriously?

Joe       No, Marie, I'm holding this box down for the hell of it.

Marie   You don't have to be sarcastic.  It's just really strange - we haven't had rats here before.

Joe       Try telling this guy that.

Marie   I mean, it’s a shitty overpriced apartment, but I didn’t think the place was that bad.

Joe       Well, clearly it is. 

Marie   Do you think we should tell the landlord?

Joe       I think we should deal with the rat first.

Marie   What was it doing?

Joe       Running across the floor.  Like a rat.

Marie   Freaky.

Joe       I know.  Will you hold this box down for me?

Marie   You don't like rats, do you.

Joe       What gives you that idea?  The fact that I am holding down a box to stop it getting free?

Marie   No, the fact that you screamed.

Joe       I did not scream-

Marie   Like a little girl, screaming in the dark.  "Eeee!  Eeee!  It's a wat!"

Joe       I did not - will you hold down this box?

Marie   Did you even catch the rat?

Joe       Of course I did.  And I didn't scream.

Marie   (Jumping on the couch) How do I know that it isn't running around somewhere?

Joe       I told you I caught it in this box.

Marie   Are you sure you did? 

Joe       Certain.  Look.

Joe very slowly takes one of his hands off the box.  He then lifts the other hand up a little, keeping contact with the box with less pressure.  Nothing happens.

Marie   Well?

Joe       Wait.

Joe taps the box with his free hand.  Suddenly, nothing at all happens.

Marie   Yeah.  A rat.

Joe       (carefully returning full pressure to the box) I’m telling you, there is a rat in there.

Marie   Well, it doesn't sound like it to me.

Joe       Maybe it's playing possum?

Marie   I thought you said it was a rat.

Joe       I did say it was a rat, but it's PLAYING possum.  Maybe it's gone to sleep.

Marie   Maybe it doesn't exist.

Joe       I came in here, I saw something too small to be a cat, with a long tail, sitting in the middle of the floor, so I calmly got this box and captured it.

Marie   In the dark.

Joe       What?

Marie   In the dark.  The lights were off.

Joe       Of course the lights were off - you don't think it would be sitting out in the open if the lights were on, do you.

Marie   I'm just saying that it was dark and you...

Joe       I what?

Marie   Maybe you just saw a shadow.

Joe       Seriously?  I saw a rat running along the floor and I caught it and you think it was a shadow?

Marie   I thought it was sitting there.

Joe       It was.  And then it ran.  It didn't stay sitting long when I came in.

Marie   I'm sorry, it's just I don't know how there could be a rat in here.

Joe       Neither do I.

Marie   We’re paying a whole lot for this place – there cannot be a rat in here.

Joe       I know.

Marie   I just can’t see how there can be a rat here when the rent is that much.

Joe       Well maybe we should ask him to pay a third?

Marie   Funny.  You're sure that there is a rat in there?

Joe       Do you want to look?

Marie   I...

Joe       Do you?

Marie   I think that would be a bad idea.  If we lift the box to look, the rat – if there is one – will escape. 

Joe       I know.

Marie   But it doesn't sound like there’s anything in there, does it?

Joe       Well, no, you're right, it doesn’t. 

Marie   Stop!

Joe       Stop what?

Marie   I know what it is!

Joe       We’ve been over this – it’s a rat.

Marie   It’s… It’s on the tip of my tongue.  It’s uncertainty!

Joe       Seriously, I am certain. 

Marie   No, I mean the theory, the principle!  Uncertainty – Heidelberg!  We can’t know exactly if it is a rat, or if it’s in the box.  I think.

Joe       I don’t know what you’re saying but I promise you I saw it, and I caught it in the box.

Marie   Just wait a minute!  There may or may not be a rat in this room... 

Joe       There's a rat.  And it's in this box.

Over the next speech, Joe relaxes his grip on the box and sits up more

Marie   Hear me out first.  Theoretically, there may or may not be a rat in this room, but we can’t exactly know or measure it.  It’s all coming back to me at last!  And if there is a rat in the room, it may or may not be in that box.  And if it is in that box, it may or may not be dead.

Joe       What?

Marie   Or asleep.  In fact, it may or may not be a rat, because we can’t measure it.

Marie continues to figure it out

Joe       Are you trying to say it’s bigger, like a possum?  Maybe… no, it can’t be.

Marie   It can’t be what

Joe       A possum.  The box isn’t big enough for a possum.

Marie   No, didn’t we just… I mean, that's not important.  It's Shrewdinger's Cat.

Joe       I said, it's a rat, not some kind of "shrewd" cat.

Marie   No, the experiment - Shrewdinger's Cat.  Remember when I did that Philosophy of Quantum Physics class?

Joe       I remember you started one.

Marie   I think that there was this thing where a scientist puts a cat in a box and it will die if you open the box, but it could be dead anyway -

Joe       (Taking one hand off the box and shaking it at little) That's just cruel.  Why wouldn't he give the cat a chance?

Marie   It was an experiment.  So the cat was in the box but because of how it worked, it was simultaneously dead and alive at the same time. 

Joe       Surely the cat was either dead or it wasn't. 

Marie   It was both.  That's the point.  Oh, and it was radiation poisoning that did it!

Joe       So it WAS dead.

Marie   Yes...  No.  It might be dead, or it might be alive.

Joe       That weird Frankenstein stuff is beyond me - why would you want to make a mutant cat?

Marie   It was to prove a point.

Joe       Yeah, well, what about this rat?

Marie   That's the thing.  We don't know.

Joe       What?

Marie   It could be a rat or not.  It could be in the box or not.  It could be dead or not.  It's all these things at the one time.  This is Shrewdingers Rat!

Joe       So, if it is Shrewdinger's Rat… shouldn’t that be it Schrödinger's Rat?

Marie   No, I'm pretty certain it's Shrewdinger's Rat.

Joe       You’re the expert.  Anyway, you admit it is a rat?

Marie   That's the point.  There's no way of knowing if it is a rat or not.

Joe       I can think of one.

Marie   What?

Joe       I could lift the box.

Marie   You wouldn't let a rat free in the house?

Joe       I could.

Marie   You couldn't!  You're frightened of them.

Joe       Yes.  Yes I am.  So no, no I couldn't.

Marie   Well, couldn’t we open the top of the box and look in?

Joe       What?  And let it jump at our faces?  Didn't you read that Orson Welles book?

Marie   Orson Welles?

Joe       (Absently takes his other hand of the box to make his points) Yeah, it was called 1964 or something.  It was about a guy in an office who has sex with some girl in a red dress and gets in trouble about it, and he gets killed by being eaten alive by rats.  Boring book, but really scary ending.  I’ll never forget it.

Marie   Do you mean George Orwell and 1984?

Joe       That makes sense - he made a film of it in 1984.  I watched it for that course on great books.

Marie   Must have been just before he died.

Joe       No, it was when I was a freshman.

Marie   I mean the film.

Joe       Sure.  Anyway, my point is, we’re not opening this box.

Marie   So, what can we to do?

Joe       Well, we can't open it.

Marie   No.  And we can't lift it.

Joe       So what are we going to do.

Marie   Isn’t this kind of the landlord’s problem?

Joe       He isn’t going to come tonight.  Or any time soon, is he?

Marie   Unless there’s like an infestation of them.

Joe       Don’t even joke about that.

Marie   I wasn’t.

Joe       So what do you think we can do?

Marie   I have no idea.

They both look at the box.  They look at each other.  They both plunge down their hands to hold the unmoving box in place.

            What time is it?

Joe       I don't know. 

Marie   You're wearing a watch.

Joe       The box!

Marie   I've got it.

Joe       Are you sure?

Marie   I am right beside you, holding it down.

Joe       Yeah.  Sorry.

Marie   It's OK.  What time is it?

Joe straightens up.  He looks at his watch and nods.  He returns to holding down the box.

Marie   What time is it?

Joe       Sorry!  (Joe once more straightens up to look at the watch)  It's quarter of. 

He bends back down to hold the box.

Marie   We gotta go.  We're due there in fifteen.

Joe       Yeah, but we can be late – the rest of the gang is always like 30 minutes late. 

Marie   Yeah, so I told you the wrong time so we didn’t have to wait around for a half hour.  What are we going to do?

Joe       I don't know.  I don't even know if it's in the box anymore.

Marie   But it might be.

Joe       But it might not.

Marie   It might not be a rat.

Joe       But it might be.

            Did Shrewdinger… Are you sure it's not Schrodinger?

Marie   Shrew.  Dinger.

Joe       OK, I don’t know why I…. Did Shrewdinger say anything about how he killed the rat.

Marie   It was radiation poisoning.

Joe       Damn!

Marie   The thing with Shrewdinger is the rat is both alive and dead.  It's there and not there.  It (recalling from the dim recesses of the memory) exists in two states simultaneously.  (Proudly) I remember that from my old textbooks.

Joe       These textbooks won't help us any now. We need to get going, and there is a rat that may or may not be in this room – or even exist – in this box.  Or not.  And it probably wants to eat our faces off.  And I didn’t even get to have sex with a woman in a red dress yet, like Orson Welles in that uni book.

Marie   Wait a minute, wait a minute!  Joe, you're a genius.  The answer is in those textbooks.  Go get my old physics textbooks and bring them here. 

Joe       But the box!

Marie   I'll hold the box.  Get those books!

He gingerly gets up and runs out.

            (Shouting after him) And get all those old lit books of yours too!

            Well, Mr. Rat!  Mr. Orson Shrewdinger!  I hope you are happy in there.  We are going to use the power of physics and literature and all kinds of education to make sure you don't escape!

            Where are you, Joe?  The books are just in the kitchen.  We need to get going!

Joe returns shortly.  He is weighed down with six massive physics text books, and five or six books of literary criticism too, of varying sizes.  He gets up onto the couch, still holding them all.  He has a very sheepish look.

Joe       Sorry, I got caught up looking at the lit books.  That book I watched was called 1984.  And you were right.  It was George Orwell.

Marie   I thought so: Orson Welles made the movie.  Now give me the physics books.

Joe hands her one.  During his speech she takes it with one hand, keeping her other hand on the box at all times.  She very carefully puts it on the box in one corner.  She then puts her hand out for another.

Joe       This is the one with quantum physics.  I didn't see anything about philosophy in any of them, but I brought them all just in case.

Marie   It doesn't matter.  Give them here.

He hands them to her one by one, naming them before he presents them, all the while she keeps one hand on the box.  She carefully covers the box with layers of books until they run out of physics books.

Joe       ‘Practical and Impractical: The Impossibility of an Antiquark and Other Tales’.

            ‘Calculus in Context’. Teachers Edition – nice!

            ‘A Mathematicians Introduction to the Theory of Relativity, 4th Edition’.

            ‘University Physics with Modern Physics’.

            ‘Intersection: The Case for the Integration of Physics, Metaphysics, and Existential Philosophy’.

Marie   OK, now give me your lit books, biggest first.

Joe       No problem, I get it.  This is probably the most good I’ve got out of them since graduation.

Marie   Same here.

She finishes covering the box and relaxes her remaining hand.  They both are more at ease.

            It should be safe now.

Joe       Just the finishing touch.

Joe gets up and goes to the table.  He gets the lamp, unplugs it and places it on top of the pile of books.  He stands back, fairly pleased. 

            That should be safe now.

Marie   Great.  Let's get going.

They start to leave.  Joe stops.

Joe       My hair!

Marie   Joe!  You can do that in the car!

Joe       Yeah, you're right.

He gets a comb and a bottle of hair product.

Marie   OK, let’s go then.

They get to the door.  Joe stops.

Joe       Wait.  What if... what if you are right and the rat is NOT in the box.  What if it’s hiding in the room somewhere?  What then?

Marie   We could... close the door?

Joe       We could close the door!  Exactly!

Neither move

Marie   And then what?

Joe       What do you mean "And then what"?

Marie   When we get back.  There may or may not be in this room something that may or may not be a rat, which may or may not be in that box, dead or asleep or something else.

Joe       Well...  Maybe we should just get a cat?

Marie nods.

Call it Heidelberg?

They both nod, Marie switches off the light and they start to go out the door.  As they depart.

Joe       You know, cats are pretty useful creatures, when you think about it. 

Marie   Sounds like that Orson Welles character would have been better off having one in that book

Joe       Yes.  I really don't know what Shrewdinger was thinking, trying to-

The door is closed.
