I especially get a chuckle out of conspiracy theory revisionist history:
- Holocaust did not occur during WW2 - Government whacked JFK instead of LHO. - Bruce Lee, Marilyn Monroe, Jim Morrison and JFK did not actually die. - Men waking on the moon was a hoax (and even fooled the Soviets) - 911 planes did not cause the towers to tumble or the pentagon explosion (inside job).
