Legend has it that Jackie Gleason, who was a UFO enthusiast, and Richard Nixon, who was a Dick, were golf buddies. One day on the links, Nixon tells Jackie he can get him in to see the aliens. And so- Nixon shows Jackie the aliens. Jackie, however, despite being the enthusiast he was, apparently began having nightmares and suffering from bouts of depression after this. Seems the grays being real was a little more than he could cope with.
