A few years ago, I attended a live-taping of "The Odd Couple" in which the creator Gary Marshall loved to interact with the audience during taping breaks.  He shared tale after tale of all the now famous people he discovered from Julia Roberts to Henry Winkler to Robin Williams.  Williams had just passed a few weeks before and Marshall gleefully spoke of how Williams' character of Mork was born on "Happy Days" because his son wanted to see a martian on the show.   Mork from Ork was only the beginning for the shooting comet we knew as Robin Williams.
