Actor Donald Sutherland is terrified of spontaneous human combustion. He always wears flame retardant clothing and has a fire extinguisher in every room of his house, and requires that all his children have a fire extinguisher in every room of their houses as well. His son, Keifer Sutherland, remembers being taught how to stop, drop, and roll before his second birthday, and that his father still requires him to perform this drill whenever he hears two sharps whistles.
