LOS ANGELES—According to details of Fear Factor creator John de Mol's will released Monday, his heirs cannot collect their inheritance until they complete a battery of challenges. "I do bequeath my estate to my wife and children, henceforth 'you,' on the condition that you fully consume the ashes from my freshly cremated corpse," the creator's will read. "Should you be able to complete the task, you will receive $10 million and a Caribbean vacation. Fail, and you'll be eliminated from my benefactors—unless you spend one hour locked in a coffin filled with maggots." Comedian Joe Rogan will serve as the will's executor.
