The key to a ghost job is inside the holy grail. outside the cave where indiana jones killed the nazis in indiana jones and the last crusade is the holy grail (Here is why the nazi's wanted the chest..supposedly Hitler wanted it). Inside the golden chest there is a white sheet, the main ingredient in the Geej. This sheet is a Ghost hunters main weapon in order to become a ghost buster and the picture evidence to not be a Danny Phantom, (poser). But the holy grail of all jobs is the ghost job.
God: I Place Thy sheet into the holy grail, so that a lucky ghost hunter can ghost bust a ho. This Job is the holy grail of all jobs. I here by send thy chest down onto the Earth.
The holy grail, holding the sacred sheet has not been found.
