Mr. Vibrating:
Come in.

Man:
Um, is this the right room for an argument?

Mr. Vibrating:
I've told you once.

Man:
No you haven't.

Mr. Vibrating:
Yes I have.

Man:
When?

Mr. Vibrating:
Just now.

Man:
No you didn't.

Mr. Vibrating:
I did.

Man:
Didn't.

Mr. Vibrating:
Did.

Man:
Didn't.

Mr. Vibrating:
I'm telling you I did.

Man:
You did not.

Mr. Vibrating:
Oh I'm sorry, just one moment. Is this a five minute argument or the full half hour?

Man:
Oh, just the five minutes.

Mr. Vibrating:
Ah, thank you. Anyway I did.

Man:

Mr. Vibrating:
Look, let's get this thing quite clear. I most definitely told you.
