The first guy, in 2007 - after too many years assuming 100,000
  people dragged big blocks straight up the sides, an engineering
  firm was like, ''Look, ppl, think about it. - they built them
  from the INSIDE OUT, duh.'' and smartly is patenting it as a
  modern construction technique because, well, no ancient
  egyptians are around to say they thought of it first. With 2
  inside out theories, I'm sure that many more will come, once
  mainstream archeology accepts what simply makes sense.
