I always loved the Bielefeld Conspiracy.Supposedly there is a city in Germany called 'Bielefeld'. But I know no one who's ever been there. And I know no one who knows someone who's ever been there. But THEY want to make us believe that the city actually exists. THEY even built autobahn signs and exits to make us believe that it exists. If you ever meet someone who claims to have been there, beware! He is one of THEM!http://en.wikipedia.org/wiki/Bielefeld_Conspiracy
There was one special on (that I actually have somewhere) that was pretty convincing in terms of the fakery evidence that they gave... things like, why did the lander not create any kind of indent if it had such powerful jets to land it smoothly, yet the ground was "a fine powder" that easy left a 2 1/2 inch impression when the first step was made on the moon?The show MythBusters (of all things) debunked many of the biggest ideas which I was shocked I'd never seen people attempt to debunk on television before (not that it never happened on tv... just that I had never seen it done)
I found it and it was called "Conspiracy Theory: Did We Land on the Moon" and aired by the FOX network here.
