People stop being morons all the time. In fact, they all become smarter than you, and you become the only comparative moron in the world.
I wish for a permanent amulet that brings me one great event of misfortune in exchange for the person below me, the one who grants my wish, being put into pain and crippling with absolutely 0% chance of undermining, reversing, deflecting, or utilizing any other fathomable form of avoidance that could comprehensibly dismantle the gesture. The amulet cannot be taken back, altered, destroyed, or in any way tranquilized from any increment of effect and accuracy that it omits. It cannot be traded or otherwise removed from my person while still retaining effect. It cannot be duplicated or rendered useless by an outside nor inside force, item, or occurrence. While the amulet is in existence, there is 0% chance of altering time in order to wipe its existence; it transcends time and space. Furthermore, science, magic, celestial/universal theories, supernatural beings, Gods/Goddesses, divine energy, or any other flavor of religious or spiritual lifework is unable to intervene with the amulet's effect. Once I am aware of the amulet (which is so through this wish), I cannot be destroyed prior to being in possession of it.
