I can't.
I make no promises.
I won't.
I have no desire to.
I mustn't.
I'll regret it if I do.
I'll never.
You will not make me.
You do?
You will not tempt me.
You are?
You must be joking.
You can?
You are pulling my chain.
Well, alright then...
Well, If you say so...
Well, if you insist...
How can't I?
Why wouldn't I?
I simply shouldn't resist.
