  M:   Ah. I'd like to have an argument, please.
  R:    Certainly sir. Have you been here before?
  M:   No, I haven't, this is my first time.
  R:     I see. Well, do you want to have just one argument, or were you thinking of taking a course?
  M:   Well, what is the cost?
  R:    Well, It's one pound for a five minute argument, but only eight pounds for a course of ten.
  M:   Well, I think it would be best if I perhaps started off with just the one and then see how it goes.
  R:     Fine. Well, I'll see who's free at the moment.
  Pause
  R:    Mr. DeBakey's free, but he's a little bit conciliatory.
  Ahh yes, Try Mr. Barnard; room 12.
  M:    Thank you.  
  (Walks down the hall. Opens door.)  
  Q:   WHAT DO YOU WANT?
  M:   Well, I was told outside that...
  Q:   Don't give me that, you snotty-faced heap of parrot droppings!
  M:   What?
  Q:   Shut your festering gob, you tit! Your type really makes me puke, you vacuous, coffee-nosed, maloderous, pervert!!!
  M:   Look, I CAME HERE FOR AN ARGUMENT, I'm not going to just stand...!!
  Q:   OH, oh I'm sorry, but this is abuse.
  M:   Oh, I see, well, that explains it.
  Q:   Ah yes, you want room 12A, Just along the corridor.
  M:   Oh, Thank you very much. Sorry.
  Q:   Not at all.
  M:   Thank You.
  (Under his breath) Stupid git!!  
  (Walk down the corridor) 
  M: (Knock)
  A:   Come in.
  M:   Ah, Is this the right room for an argument?
  A:   I told you once.
  M:   No you haven't.
  A:   Yes I have.
  M:   When?
  A:    Just now.
  M:   No you didn't.
  A:   Yes I did.
  M:  You didn't
  A:   I did!
  M:  You didn't!
  A:   I'm telling you I did!
  M:  You did not!!
  A:   Oh, I'm sorry, just one moment. Is this a five minute argument or the full half hour?
  M:  Oh, just the five minutes.
  A:   Ah, thank you. Anyway, I did.
  M:  You most certainly did not.
  A:   Look, let's get this thing clear; I quite definitely told you.
  M:  No you did not.
  A:   Yes I did.
  M:   No you didn't.
  A:   Yes I did.
  M:   No you didn't.
  A:   Yes I did.
  M:   No you didn't.
  A:   Yes I did.
  M:  You didn't.
  A:   Did.
  M:  Oh look, this isn't an argument.
  A:   Yes it is.
  M:   No it isn't. It's just contradiction.
  A:   No it isn't.
  M:  It is!
  A:   It is not.
  M:  Look, you just contradicted me.
  A:   I did not.
  M:  Oh you did!!
  A:   No, no, no.
  M:  You did just then.
  A:   Nonsense!
  M:  Oh, this is futile!
  A:   No it isn't.
  M:  I came here for a good argument.
  A:   No you didn't; no, you came here for an argument.
  M:  An argument isn't just contradiction.
  A:   It can be.
  M:  No it can't. An argument is a connected series of statements intended to establish a proposition.
  A:   No it isn't.
  M:  Yes it is! It's not just contradiction.
  A:   Look, if I argue with you, I must take up a contrary position.
  M:  Yes, but that's not just saying 'No it isn't.'
  A:   Yes it is!
  M:   No it isn't!
  A:   Yes it is!
  M:  Argument is an intellectual process. Contradiction is just the automatic gainsaying of any statement the other person makes. 
  (short pause) 
  A:  No it isn't.
  M:  It is.
  A:  Not at all.
  M:  Now look.
  A: (Rings bell)  Good Morning.
  M:  What?
  A:   That's it. Good morning.
  M:   I was just getting interested.
  A:   Sorry, the five minutes is up.
  M:  That was never five minutes!
  A:   I'm afraid it was.
  M:  It wasn't.
(Pause)
  A:   I'm sorry, but I'm not allowed to argue anymore.
  M:  What?!
  A:   If you want me to go on arguing, you'll have to pay for another five minutes.
  M:  Yes, but that was never five minutes, just now. Oh come on!
  A:  (Hums)
  M:  Look, this is ridiculous.
  A:   I'm sorry, but I'm not allowed to argue unless you've paid!
  M:  Oh, all right. 
  (pays money) 
  A:   Thank you.
  short pause
  M:  Well?
  A:   Well what?
  M:   That wasn't really five minutes, just now.
  A:    I told you, I'm not allowed to argue unless you've paid.
  M:   I just paid!
  A:   No you didn't.
  M:   I DID!
  A:   No you didn't.
  M:  Look, I don't want to argue about that.
  A:  Well, you didn't pay.
  M:  Aha. If I didn't pay, why are you arguing? I Got you!
  A:   No you haven't.
  M:  Yes I have. If you're arguing, I must have paid.
  A:   Not necessarily. I could be arguing in my spare time.
  M:  Oh I've had enough of this.
  A:   No you haven't.
  M:  Oh Shut up.  
  (Walks down the stairs. Opens door.)  
  M:  I want to complain.
  C:  You want to complain! Look at these shoes. I've only had them three weeks and the heels are worn right through.
  M:  No, I want to complain about...
  C:   If you complain nothing happens, you might as well not bother.
  M:  Oh!
  C:   Oh my back hurts, it's not a very fine day and I'm sick and tired of this office.  
  (Slams door. walks down corridor, opens next door.)  
  M:  Hello, I want to... Ooooh!
  H:   No, no, no. Hold your head like this, then go Waaah. Try it again.
  M:  uuuwwhh!!
  H:   Better, Better, but Waah, Waah! Put your hand there.
  M:  No.
  H:   Now..
  M:  Waaaaah!!!
  H:   Good, Good! That's it.
  M:  Stop hitting me!!
  H:  What?
  M:  Stop hitting me!!
  H:   Stop hitting you?
  M:  Yes!
  H:   Why did you come in here then?
  M:   I wanted to complain.
  H:   Oh no, that's next door. It's being-hit-on-the-head lessons in here.
  M:  What a stupid concept.
