"Mork & Mindy" is a t.v. series that had aired from 1978 to 1982. The word "Na-Nu Na-Nu" is a greeting given by the main character of the show Mork, an alien from the planet Ork. (pronounced /ˈnɑ nu ˈnɑ nu /) The greeting is also accompanied along with a hand gesture similar to Mr. Spock's Vulcan salute from Star Trek, combined with a special handshake.
"I am Mork from Ork. Greetings, I come in peace, Na-Nu Na-Nu....!!!"
