Lifting a 22,000 pound rock pillar without any equipment at all. Was on History Channel a while back and if you didn't see it and have ten or so minutes take a look. Totally awesome. He demonstrates how a basically stone age culture could have built Stonehenge with no tools whatsoever. However if those stone age assholes had the brains to perform this feat they wouldn't have been stone age, they'd have been post industrial and hired Mexicans or Panamanians to do the work.
