My evil play would be to remove all aglets from shoelaces around the world.
Soon, people will begin tripping over themselves, unable to walk anywhere without stumbling. It will become an international epidemic. Billions will hurt themselves in the first week, unable to walk properly. Soon the death number will begin to rise, with no end in sight. Scientists won't be able to stop it either, as they will have tripped while walking to their car and broken their backs. (No, life alert will be disabled as well, before you ask). Within a month, national leaders will be begging me to give them aglets back, to end their suffering. And they will give me anything to do it. Including THE STATUE OF LIBERTY. And a few billion dollars as well. With that money, I will turn the Statue of Liberty into a walking death machine, and use it to take over the world!
It's a flawless plan, really.
