Moment From The Princess Bride

The battle of wits
Westley engages Vizzini in a battle of wits. He fills two goblets with wine and tells Vizzini that one contains a deadly poison called iocane powder, challenging him to work out which one.
In this enchantingly cracked fairy tale, the beautiful Princess Buttercup and the dashing Westley must overcome staggering odds to find happiness amid six-fingered swordsmen, murderous princes, Sicilians and rodents of unusual size. But even death can't stop these true lovebirds from triumphing.
