A magician named Rich Ferguson posted a video on YouTube to show off one of the better Halloween costumes we've seen. --It's him showing it off to people, and at first glance, it doesn't even LOOK like a costume. But then he pretends to sneeze, and his HEAD FALLS OFF. --It's so realistic, almost everyone he shows it to freaks out, then cracks up. (--Search for "Craziest Halloween Prank Head Drop Illusion."
