Get Cracking-What Was It About EGGS in the Seventies?

Have you ever noticed how obsessed people were in the seventies with eggs? No, not scrambled and over-easy, but the shape. Look at these seemingly unrelated things and how they all somehow involved the shape of an egg.  Mork from Ork, played by lovable Robin Williams hatched out of space egg. People decided for some reason that those flat pantyhose packages just weren't cutting it and thought it would be smarter to package them into egg-shaped dome, like  "L'Eggs".   As if that weren't enough, they also though that sitting in an egg would be interesting, hence the "egg-chair" was born. Remember that scene from the movie "Dazed and Confused" where those kids are sitting in an egg-chair?  Perhaps this is a mystery that will never be explained, but it is rather puzzling.
