What a classic! We love this movie in our house. Today I felt like we had taken a page out of the book. John and Audrey were sharing a Sobe. Our rule is the person who divides the treat allows the other person to choose. So the person doing the dividing usually tries to make it pretty fair. It seemed that Audrey was in the science lab doing an experiment or something...she had two glasses and was literally putting a drop in one and a drop in the other one to make sure they were as even as possible. And taking a long time. Once she finished, John did not even spend any time thinking about it, but just grabbed the glass in front of him. So I said - "Clearly you could only choose the drink in front of you". 
At which time my husband started quoting the lines from the Princess Bride and doing quite a good rendition of Vizzini! For those needing a chance to review, here is a snippet from the movie:--------------------------------------------------------------------------------
Man in Black: All right. Where is the poison? The battle of wits has begun. It ends when you decide and we both drink, and find out who is right... and who is dead.
Vizzini: But it's so simple. All I have to do is divine from what I know of you: are you the sort of man who would put the poison into his own goblet or his enemy's? Now, a clever man would put the poison into his own goblet, because he would know that only a great fool would reach for what he was given. I am not a great fool, so I can clearly not choose the wine in front of you. But you must have known I was not a great fool, you would have counted on it, so I can clearly not choose the wine in front of me.
Man in Black: You've made your decision then?
Vizzini: Not remotely. Because iocane comes from Australia, as everyone knows, and Australia is entirely peopled with criminals, and criminals are used to having people not trust them, as you are not trusted by me, so I can clearly not choose the wine in front of you.
Man in Black: Truly, you have a dizzying intellect.
Vizzini: Wait til I get going! Now, where was I?
Man in Black: Australia.
Vizzini: Yes, Australia. And you must have suspected I would have known the powder's origin, so I can clearly not choose the wine in front of me.
Man in Black: You're just stalling now.
Vizzini: You'd like to think that, wouldn't you? You've beaten my giant, which means you're exceptionally strong, so you could've put the poison in your own goblet, trusting on your strength to save you, so I can clearly not choose the wine in front of you. But, you've also bested my Spaniard, which means you must have studied, and in studying you must have learned that man is mortal, so you would have put the poison as far from yourself as possible, so I can clearly not choose the wine in front of me.
