Just impossible to pick a favourite Tim, but so much of it is in the timing, and where timing is concerned this one gets the prizes: (sorry so long)
The argument room:

Man: Is this the right room for an argument?
Other Man: (pause) I've told you once.
Man: No you haven't!
Other Man: Yes I have.
Man: When?
Other Man: Just now.
Man: No you didn't!
Other Man: Yes I did!
Man: You didn't!
Other Man: I did!
Man: You didn't!
Other Man: I'm telling you, I did!
Man: You didn't!
Other Man: (breaking into the developing argument) Oh I'm sorry, is this a five minute argument, or the full half hour?
Man: Ah! (taking out his wallet and paying) Just the five minutes.
Other Man: Just the five minutes. Thank you. Anyway, I did.
Man: You most certainly did not!
Other Man: Now let's get one thing perfectly clear: I most definitely told you!
Man: Oh no you didn't!
Other Man: Oh yes I did!
Man: Oh no you didn't!
Other Man: Oh yes I did!
Man: Oh no you didn't!
Other Man: Oh yes I did!
Man: Oh no you didn't!
Other Man: Oh yes I did!
Man: Oh no you didn't!
Other Man: Oh yes I did!
Man: Oh no you didn't!
Other Man: Oh yes I did!
Man: No you DIDN'T!
Other Man: Oh yes I did!
Man: No you DIDN'T!
Other Man: Oh yes I did!
Man: No you DIDN'T!
Other Man: Oh yes I did!
Man: Oh look, this isn't an argument!
(pause)
Other Man: Yes it is!
Man: No it isn't!
(pause)
Man: It's just contradiction!
Other Man: No it isn't!
Man: It IS!
Other Man: It is NOT!
Man: You just contradicted me!
Other Man: No I didn't!
Man: You DID!
Other Man: No no no!
Man: You did just then!
Other Man: Nonsense!
Man: (exasperated) Oh, this is futile!!
(pause)
Other Man: No it isn't!
Man: Yes it is!
(pause)
I came here for a good argument!
Other Man: AH, no you didn't, you came here for an argument!
Man: An argument isn't just contradiction.
Other Man: Well! it CAN be!
Man: No it can't!
An argument is a connected series of statement intended to establish a proposition.
Other Man: No it isn't!
Man: Yes it is! 'tisn't just contradiction.
Other Man: Look, if I argue with you, I must take up a contrary position!
Man: Yes but it isn't just saying "no it isn't".
Other Man: Yes it is!
Man: No it isn't!
Other Man: Yes it is!
Man: No it isn't!
Other Man: Yes it is!
Man: No it ISN'T! Argument is an intellectual process. Contradiction is just the automatic gainsaying of anything the other person says.
Other Man: It is NOT!
Man: It is!
Other Man: Not at all!
Man: It is!
DING! (the arguer hits a bell on his desk and stops.)
Other Man: Thank you, that's it.
Man: (stunned) What?
Other Man: That's it. Good morning.
Man: But I was just getting interested!
Other Man: I'm sorry, the five minutes is up.
Man: That was never five minutes!!
Other Man: I'm afraid it was.
Man: (leading on) No it wasn't.....
(pause)
Other Man: (dirty look) I'm sorry, I'm not allowed to argue any more.
Man: WHAT??
Other Man: If you want me to go on arguing, you'll have to pay for another five minutes.
Man: But that was never five minutes just now!
(pause... the Other Man raises his eyebrows)
Oh this is...
This is ridiculous!
Other Man: I told you... I told you, I'm not allowed to argue unless you PAY!
Man: Oh all right. (takes out his wallet and pays again.) There you are.
Other Man: Thank you.
Man: (clears throat) Well...
Other Man: Well WHAT?
Man: That was never five minutes just now.
Other Man: I told you, I'm not allowed to argue unless you've paid!
Man: Well I just paid!
Other Man: No you didn't!
Man: I DID!!!
Other Man: YOU didn't!
Man: I DID!!!
Other Man: YOU didn't!
Man: I DID!!!
Other Man: YOU didn't!
Man: I DID!!!
Other Man: YOU didn't!
Man: (unable to talk straight he's so mad) I don't want to argue about it!
Other Man: Well I'm very sorry but you didn't pay!
Man: Ah HAH!! Well if I didn't pay, why are you arguing??? Ah HAAAAAAHHH! Gotcha!
Other Man: (pause) No you haven't!
Man: Yes I have!
If you're arguing, I must have paid.
Other Man: Not necessarily.
I could be arguing in my spare time.
