Here is what I would do.
I would start by making an example of the most famous dick in the world, Ron Jeremy.
I would warn him through an anonymous twitter account that in 30 days his dick would shrink. Ron would of course laugh at this. He has a big dick. He is superior and invincible. His dick can never shrink. But I would continue making my threats and as they got more press, Ron would see a business opportunity. Believing that nothing would happen, he would do a live stream of his shrinking. His plan would be to entertain his fans by mocking the idea of his giant dick ever shrinking and showing it being worshipped by a harem of hot porn girls. Hundreds of thousands of people across the world would pay to see this event.
But on that day, as his harem are all rubbing on his member, I will write his name in the notebook and in front of the crew filming, his porn star harem and the thousands watching online Ron Jeremy's dick would shrink down to nearly nothing.
The world would be shocked and on edge as all men would start fearing for the safety of their dicks. It would be then that I would make my first demands.
