You have the ability to control any person in the world for one minute, what do you do with this ability?
Only one time use.
Think of like world leaders, celebrities, ya know π. Are you gonna make them do some embarassing things, or illegal acts.
My answer:

Take control of an NSA agent with access to the most powerful hacking tools, hack everyone's phone, install a program that randomly have a popup at random intervals, the popup message says "I'm watching you". This also tries to spread itself to any other phone it can connect to. Pure chaos π
Pretty sure I can do this in a minute, depending on how good the NSA tools are.
