Most people know that Men Who Stare at Goats was based on a non-fiction book by Jon Ronson, and that some of the most preposterous parts of the movie were reportedly the most faithful to things
that really happened. Before it was a book or a movie, Men Who Stare at Goats was a Channel 4 documentary series, The Crazy Rulers of the World. In the above clip from the show, you can see Ronson, who talks like Little Lord Fauntleroy, interview the guy who claims to actually have knocked a goat down with his mind from an adjacent room. His superiors later bring in 30 numbered goats, and ask him to use his mind bullets again on a specific goat. He fails, but only because he took down the goat next to the goat he was supposed to.
