Oh, well it must be true
I know a guy who is utterly convinced that the moon landings were faked. Why? Because when someone ran up to Buzz Aldrin with a bible in hand and asked him to swear on it that he had been to the moon, Aldrin punched him in the face. He takes this as proof that the landings never happened because:

"He couldn't swear on the bible that it happened, so he HAD to punch the man in the face".

*Edit - Aldrin, not Armstrong*

I'm firmly of the opinion that the guy fully deserved that punch

Wrong astronaut
It was Buzz Aldrin, second man to walk on the moon, who smacked the annoying guy in the face. And quite right too.

Buzz Aldrin.
Most justified conspiracy loon punch in the history of punching conspiracy loons.
