The one that absolutely drives me bonkers are those that believe we didn't land on the moon...
I always ask them:
Who were we in a space race with at the time? answer ... USSR
Do you think we were friendly with the USSR at the time or were we enemies? answer...enemies
Do you think the USSR back then and up until the fall of the USSR, and Russia today would let us get away with this huge Conspiracy? answer..."what do you mean?" ....dumb asses.
IF we never landed on the moon and NASA staged this whole thing in Hollywood, that means that the USSR, China, Japan, Great Britain, France, Luxembourg, Switzerland, Germany, Canada, Iceland, Ghana, Gabon, Egypt, Isreal, Iran, India, Vietnam, etc etc etc....the whole FRIGGIN' world is involved in this and all of their governments are covering up the fact that we...the USA...never landed on the moon. I cannot believe that there is anyone, in this country, that believe they are completely sane, actually believe that we never landed on the moon!
The best thing about those people is that they make this here idiot feel good about his IQ.
