A celetoid is only allowed so much time in the spotlight. Of course, just when you think your life as a celetoid has passed, you end up writing an article about your experience six years later, or you sing a song for a friend at a wedding.
British Big Brother contestant Jane Goody is another who achieved celetoid fame which was extended, as Lawler's was, through the shift from ordinary competitor to contestant on celebrity relaity shows.
