Interesting theory from Bovine Inversus regarding Jim Carrey and Andy Kaufmann:
"This is my theory regarding Andy Kaufman: Keeping in mind that Jim Carrey made his first film appearance in 1984, the year that Andy Kaufman died - Kaufman faked his death and underwent extensive plastic surgery in order to look like Jim Carrey. Knowing that he had it in him to become a famous actor (again), he anticipated that he would star as himself in Man on the Moon, which opens Christmas '99, at the premier of which he will, after 15 years of fooling everybody, announce that he is in fact Andy Kaufman."
