The Invisible Man; Sighted
We saw a couple of variations on this one while in Rome. Men, or women, put on an oversized suit (think David Byrne in Stop Making Sense) that hides their head inside the shirt and jacket. They attach a floating hat and sunglasses so that it seems as if the invisible man is sitting before you. It was hilarious watching this little boy as the tried to figure out what happened to this guy's head and, more importantly, whether or not he should shake hands. He never did.
