Wayne Campbell (Wayne's World) can bend the universe to his will
Everything he says he wants or desires he gets. From the beginning of the first movie with the Fender guitar (It will be mine) to Cassandra, to wanting to get paid for his show, he states to the universe that he wants it and it becomes his.share
Since he's immature and stops concentrating, he has issues come up (Cassandra running away with Benjamin, Friends and Garth leaving him), but as soon as he says he wants things fixed, they are.
He also is able to open a door in Stan Mikita's donut shop and there are magically ninja special forces training simply because Wayne has always wanted to open a door with people training like in James Bond.
Looking at the second movie, how impossible is it to just decide to put on an outdoor festival with the biggest names in music. Wayne says he's putting on a concert, and the likes of Aerosmith and Rip Taylor will be there. He's a nobody in the music world, yet just makes some calls and has a little press and these huge bands show up. Even Jim Morrison tells him if he books them, they will come. How will Wayne Campbell call people to book major bands for a spur of the moment event?
And the capping evidence, in both movies, Wayne can decide on a whim to change the ending. Don't like the original ending? Let's try the Scooby Doo ending. That was fun but still not right. Let's try the mega happy ending.
