INCONCEIVABLE! 
I am waiting for you, Vizzini! You told me to go back to the beginning… so I have. 
I just want you to feel you’re doing well. I hate for people to die embarrassed. 
Please consider me as an alternative to suicide. 
Don’t bother me with trifles. After 20 years, at last my father’s soul will be at peace. There will be blood tonight! 
You be careful. People in masks cannot be trusted. 
I will never love again. 
You can’t hurt me. Westley and I are joined by the bonds of love. And you cannot track that, not with a thousand bloodhounds, and you cannot break it, not with a thousand swords. And when I say you are a coward it is only because you are one of the slimiest weaklings ever to walk the Earth! 
I don’t think I’m quite familiar with that phrase. 
We are men of action, lies do not become us.
