Mork's Orkan Greeting - The sitcom MORK AND MINDY/ABC/1978-82 featured a zany alien called Mork (Robin  Williams) from the planet Ork who lived with earthling Mindy McConnell (Pam Dawber) in Boulder, Colorado. In a parody of the Vulcan greeting from the sci-fi drama STAR TREK/NBC/1966-69, Mork placed his palm straight out in a regular handshake position and then did a scissors motions separating his middle and ring fingers followed by the greeting "Na-Nu, Na-Nu". When he reported into his galactic supervisor back on Ork he said "Mork calling Orson. Come in Orson...Yoo-hoo! Come in Hippo Hips!" See also "Orson from Ork".
