A call from a friend prompted me to search for the site called “peter answers”. Initially there was no sane explanation to explain how my friend was describing how the site was giving him exact answers to the questions he was asking.
A little research of course laid bare the M.O.behind asking questions and getting those answers. You need to build a little myth around peter just so that everyone gets into the mood, but once you start demonstrating the powers of Peter and get everyone involved it should be fun
A great prank! Try it out here
