Indeed, social retard here. It's quite an epic analogy. It's from the Princess Bride. In that scene, the old guy is holding the princess hostage. Old guy claims to be epic planner. He agrees to hold a contest of wits. If the hero wins, he gets the girl. If the evil guy wins, hero dies.
The hero suggests this as the game of wits: here are two cups with water. One is poisoned. This one is mine. Figure out which cup is the poisoned one. We drink both at once.
He starts talking about whether he give himself or his enemy the poisoned cup, does bullshit reasoning to figure it out. He picks one, drinks, and dies. Hero explains to chick that both were poisoned. He purposefully took small doses over the years to develop an immunity.
