Good old Bigfoot. First he does then he doesn't exist. I could have sworn that climber Reinhold Messner who first claimed to have come face to face with a Yeti went on to say it was a black bear, but I couldn't find the story. Now, however, a police expert claims he has 'proof' Bigfoot exists.

Of course, it was only a week ago when a row erupted between the Nepalese and a Japanese scientist who claimed that the yeti was nothing more than a case of linguistic mistaken identity
