Well, not exactly. The Georgia Bureau of Investigation has the remains of pretty funny hoax from 1953. Pranksters took a dead monkey, cut off its tail, used hair remover to make the little guy bald and died him green. Then told the UFO crazed public it was a Martian Monkey. The rascals even burnt a ring into the pavement with a blowtorch, simulating a small spacecraft landing.
According to the story:
Barbers Edward Watters and Tom Wilson, and the butcher, Arnold "Buddy" Payne, told the policeman they came upon a red, saucer-shaped object in the road that night. They said several 2-foot-tall creatures were scurrying about and the trio hit one with their pickup before the other creatures jumped back in the saucer and blasted skyward - leaving the highway scorched.
Nothing like a good old fashioned hoax.
