Sibrel's single, most notable work is a 47-minute video work likewise calling into question the historicity of the Apollo moon missions; entitled "A Funny Thing Happened on the Way to the Moon", Sibrel describes the Apollo program as a "Cold War CIA and Nixon administration deception." Amanda Hess, writing for "The New York Times" alludes to the work as a pseudo-documentary, and describes the work in this way: "It mashed up moon footage with ominous shots from the Soviet Union and Vietnam, was narrated by a severe British woman and was sold on a website called MoonMovie.com." Sibrel confronted several Apollo astronauts in the preparation of his videos, all of whom responded indifferently or negatively when they realized that they were being challenged on their achievement of landing and walking on the Moon.
