Forty-seven years ago today, in 1969, Neil Armstrong and Buzz Aldrin became the first people to set foot on the moon. Even though we can still see pieces of equipment we left up there, even though we have moon rock samples sitting in museums, there are still people who don't believe it happened.
So on the anniversary of the day the first humans actually walked on the moon, lets all remember the time Aldrin got so sick of conspiracy theorists that he punched one in the face.
In 2002, filmmaker and conspiracy theorist Bart Sibrel confronted Aldrin with a video camera and demanded that he swear on the Bible that the moon landing really happened.
You can hear Sibrel call him a coward, a liar and a thief — just before Aldrin shuts him up.
Aldrin was never charged for anything — arguably fair, considering he risked his life for the sake of science and exploration.
You can watch the build-up to the punch in the video below:
