If Jesus or Tupac ever finally return like we’ve all been saying they will, they should probably do it in a Judd Apatow film or something like that. We love cameos, don’t we? It’s especially delightful when it’s extremely unexpected, and of course extra points if they are playing themselves – or better yet some kind of silly version of themselves. It’s all about recognizing the kind of person you are perceived to be, and then playing off that in a way that makes the audience realize that you are in on the joke. If a celebrity is able to do that, it’s instant coolness.
