The Phantom Whistler!
- Find a really great roof; two-story works really well.
- Wait until someone is walking by on the ground.
- Begin whistling. (Any song will do, but make sure it's a song and not just random whistling.)
- Watch the confusion.
Your victims will look side to side, behind, and all around. But they will NOT look up, ever. If your victims look up, they are not normal humans. Do not be fooled. Humans think the world is ten feet tall. Anything that comes from above that does not exist. The sky is a pretty picture on the ceiling. Buildings, unless they are in them, extend above their heads only in theory. Thus, if they hear a sound coming from somewhere that is not around them, it is a phantom sound that they cannot identify. They will either slow down, confused, or they will speed up and try to get out of there to avoid being disturbed further. They will forget about it very soon.
Should the person see you (or, unbelievable as it might seem, should the person call up to you in a friendly fashion), you should immediately befriend this wonderful person and offe lessons on how to play The Phantom Whistler.
