INCONCEIVABLE! 
I just want you to feel you’re doing well. I hate for people to die embarrassed. 
I am waiting for you, Vizzini! You told me to go back to the beginning… so I have. 
You be careful. People in masks cannot be trusted. 
Please consider me as an alternative to suicide. 
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 only dog paddle. 
I don’t think I’m quite familiar with that phrase. 
Don’t bother me with trifles. After 20 years, at last my father’s soul will be at peace. There will be blood tonight!
