In this brand new interview, Jay Leno shares some of Robin Williams' greatest qualities.

While Robin Williams started performing standup comedy in the mid’70s, most of America first fell in love with him as the naïve and hilarious alien from the planet Ork in Mork & Mindy. He became an instant superstar and went on to do five HBO standup specials and dozens of feature films. Robin performed steadily for nearly four decades—from comedy clubs to stadiums, from talk shows to USO tours—and continually amazed audiences with his frenetic energy and unbelievably quick wit.
