"When he auditioned for the role of Mork from Ork on Happy Days (1974), producer Garry Marshall told him to sit down. Williams immediately sat on his head on the chair. Marshall hired him, saying that he was the only alien who auditioned. During the making of Mork & Mindy (1978), Williams departed from the scripts and ad libbed so many times and so well, that the producers stopped trying to make him stick to the script and deliberately left gaps in the later scripts leaving only, "Mork can go off here" in those places so Robin could improvise. … Asked by James Lipton about what he would like God to say when he arrives in heaven, Williams answered that "There is a seat in the front" in the concert of Wolfgang Amadeus Mozart and Elvis Presley."
