Post-It

Lets pretend two things:

1. Heaven is real, everyone gets in and you can watch what happens on earth.
2. I have invented something great that are used everyday, lets say... post-it notes

If these two things happened then I would make sure to write in my will that only family member at a time can inherit the money earned from the copyright of my invention. And they would not be allowed to share the money with anyone else. Then when I died I would spend the rest of eternity watching as they destroyed each other over the money.
Pure, everlasting entertainment!
