We normally do not place this type of cache container, but came across the location and could see one would fit here just right.
Mork & Mindy is an American television sitcom that aired on ABC from September 14, 1978, to May 27, 1982. It starred Robin Williams as Mork, an extraterrestrial who comes to Earth from the planet Ork.
Mork's catchphrase was “Nanu, Nanu,” words that had multiple uses in the TV series, but no exact definition. When communicating with his leader, he would say “Nanu Nanu” when signing off. He would also use it as a greeting, like Hello or Goodbye.
