Amateur scientist Gordon Holmes videotaped something in Loch Ness. Could it be the famous monster? See the video and judge for yourself. Kinda looks like a log to me.
If you'd like to know more about the guy who faked a famous photo and then confessed to the stunt on his deathbed, read Great Moments in Science's entry on the Loch Ness Monster. It provides interesting background on Christian Spurling, who helped convince the world of Nessie's existence with just a toy submarine, some wood putty and a respectable witness.
