In The Princess Bride, at the very end, the Grandson asks the Grandfather to come back and read the story again. The Grandfather replies, "As you wish," which seems very sweet but not particularly dramatic—until you remember what was said earlier: "When he said 'As you wish,' what he meant was 'I love you.' "
The famous I Am Not Left-Handed scene. Why does Westley take the sword in his left hand to start with? Well, in fencing, lefties have a natural advantage against righties simply because few people train to fence against lefties. When a lefty fences a lefty they are both used to fencing against righties, hence both have a disadvantage. BUT if you are a lefty who has experience against other lefties, then you would be at an advantage against a lefty who had mainly trained against righties. So clearly Westley had experience fighting against lefties as a lefty and used his left hand in order to cancel out Inigo's advantage. —Lawyer Dude
I don't know if this makes this less brilliant/logical or not, but, as both men are absolute masters of the fencing art, could it be simply that, to give their opponent a chance (albeit just a sliver of a chance), each man took what was his "weak" hand, that being the left. As Fezzik might say, "It's more sportsmanlike". — wacomason
They were both explicitly stretching it out in the book, as well as feeling out their opponent more thoroughly.
Considering they were both masters of fencing, how did Westley and Inigo not realize that the other was not left handed. This is especially true on Westley's part as Inigo sits in front of him for several moments with his sword sheathed on his LEFT hip; drawing it with his right both to show the blade to Westley during his story and again before transferring the sword to his left before the duel fights. Any trained swordsman would know that your sword is generally worn opposite your dominant hand. Westley averts this in that his sword was slung behind his back (and he began to draw it with his left hand by reaching behind him) though this was probably due to climbing the cliffs.
Who's to say Westley didn't know? He didn't seem too surprised in the movie at least (I forget if that was touched on in the book).
Vizzini actually gets it right during the Battle of Wits: neither cup is safe. Sure, he might just be stalling, but it actually seems like he figures it out when you stop to think about it.
Wesley got him with Exact Words. Remember, he said, "Where is the poison?" not "Which cup has the poison?" Vizzini just assumed that one cup was poisoned since he knew the Man in Black was trying to kill him, but also take the princess.
It gets better when you realize that all of the implication that both cups are poisoned are in his body language, not his words. Everything he says is Exact Words, but what he does - switching the cups around before putting them on the table - implies that one or the other has it.
The point is Vizzini doesn't figure it out—he might get it right, but he doesn't realize it.
Fridge Horror. Westley is the good guy, but how many innocent sailors has he killed while being the Dread Pirate Roberts?
It's implied that the Dread Pirate Roberts is more about reputation than anything. The whole point of the name was to get the crews of enemies to surrender, rather than fight. The idea is, "If you fight, we kill you all, no exceptions. If you surrender, we take your stuff."
Possible Fridge Brilliance here. Apparently, medieval pirates would often attack ships near coasts. The victim crew (especially if they had no financial interest in the ship) would often just abandon the ship rather than fight the pirates. If the pirates never lost or took prisoners, they'd be even more likely to just give them the ship.
The reason for the numerous killings is so that, when the title of Dread Pirate Roberts is passed on, there will be no one who could recognize that the new DPR isn't the same one that held up their ship before. Westley likely has a bodycount in the hundreds, if not thousands, in order to maintain the charade.
It's explicitly stated that when Westley was trained, they put the crew off at the next port and hired new ones. In an era before cameras and TV, the odds of a random sailor crossing your path and figuring out your secret are pretty low. Plus, it's one crew in five years, there's not a lot of people out there who could identify him.
This Troper always got a chuckle out of Buttercup rolling downhill after Wesley when she shoved him down after realizing it was him, primarily because she could easily have just ran after him. But then, while watching the ex-reviewer formerly known as VixenOfNine's review of the film he remembered a certain line from that scene: "You mocked me once, never do it again! I died that day! And you can die too for all I care!" Give up? She expected the fall to kill him, meaning that when she sent herself falling after him she was hoping to kill herself too!
The book lessens this one considerably: Westley doesn't say "As you wish" until he is at the bottom of the ravine, and is pulling off his mask — not when he is in the process of tumbling down. So when Buttercup launches herself after him, she knows it's not a deadly fall.
I never quite got Vizzini's strategy in the Battle of Wits. I mean, okay, so he's not as clever as he thinks, but still, what kind of plan is "come up with some convoluted reason why the cup was his or Westley's"? Even switching the cups wouldn't matter in that case, really. But then I realized two things: first, all his pre-choice ramblings were really an attempt to get Westley to reveal something, even subconsciously - but Westley could afford to be completely serene and confident, since he knew he would win either way. Second, of course, Vizzini waits until Westley takes a good long chug from his goblet before he takes a sip (while smirking). Plan A having failed, he switched the cups and decided just to see what Westley would do, sure that his opponent hadn't noticed. (Although I am pretty sure Westley took his time "looking in the other direction".) of course, he completely failed to realize that his blunder was simple - in a fight to the death, never let your opponent choose the rules.
Fridge Horror: Humperdinck wants the crown and to take over the world. So, he plots to start a war with his enemies by framing them for the murder of his wife. It doesn't seem that far off from him wanting the crown by slowly killing his own father, using a poison like mercury to drive him to slow insanity. The reason he got rid of Miracle Max? So Max cannot discover the truth of his heinous crimes.
Fridge Logic: When Wesley is screaming the Sound of Ultimate Suffering, Inigo tells Fezzik he knows it's the Man in Black because "his true love marries another tonight." How does Inigo know that Wesley/the Man in Black is the True Love of Buttercup? The whole of their interaction before that scene was the duel, and the majority of their conversation during that was informing each other of how they weren't left-handed.
Perhaps Inigo is Genre Savvy enough to realize that no man in such a fairy tale land could have accomplished all the inconceivable feats the Man in Black had except to save his true love.
Also, Fezzik was filling him in on the details while nursing Inigo to health.
Specifically, on the eve of the Royal Wedding, who in the land has cause to cry out with Ultimate Suffering but the man whose true love is, in fact, the Royal Bride?
Fridge Logic, and certainly deliberate: there are five kisses that "everyone" agrees deserve full marks, and this one left them all behind. There most have been some really infallible witnesses to those kisses for historians to be able to compare and judge them like that.
It's like the list of the World's Most Beautiful Woman, which is brought up all the time in the books. What standard of beauty are they using? Who's keeping track, when we have candidates all the way from England to India? How long is the list? Who is keeping this list?
Fridge Logic: The boy's father is probably either dead or absent for some reason. At the beginning, the grandfather says that his father (the boy's great-grandfather) used to read him The Princess Bride when he was sick, and he used to read it to the boy's father when the boy's father was sick.... so if it's a father-to-son tradition, why isn't the boy's father around to read the book to him?
