Rather simple game (I got from 'Whose Line Is It Anyway'). Every comment has to be a question in reply to the person before you.
Person 1: Who are you?
Person 2: Would it matter?
Person 1: Are you being hostile?
Person 2: Would you like me to be?
Why should anyone do anything?
should we really be asking such a ridiculous question?
Surely, you agree with J.B Priestly phiolsothly? (Excuse the spelling)
which philosophy might that be?
Did you receive an education?
what kind of question is that?
Are you implying that I am unintelligent?
why would you think something like that?
How is that not obvious?
Why are you trying to confuse me?
are you seriously getting confused by this?
