Sticky Loch Ness Monster

Saw a documentary at National Geographic channel. They did a simple test. Had a log floating at Loch Ness and asked the tourists what it looked like. Some of them said it could have been Nessie, some of them said it was a stick. Had the same log at another body of water (away from Loch Ness) and then asked around what it was. All of them said a definite 'stick'. Shows that expectations and the mind could play a trick on us.
