That this inhabitant of planet Mars resembles Ernie, one half of Sesame Street's Bert & Ernie brotherhood that turned up in the July 1969 pilot episode, could be more than a coincidence a la 911 innuendo turning up in The Simpsons for instance, and could mean there were either rovers or Manned missions before the first landers officially arrived in the 1978 Mars Viking Program.

As well as a Martian this frame from Curiosity Sol 300 has a stone face.
