A routine colonoscopy at the Dover Family Clinic in no way evoked the Isaac Asimov novel Fantastic Voyage or its 1966 film adaptation, patient Ed Garrity reported Monday. 'Man, this really isn't anything like the movie,' said Garrity, 54, watching the interior of his large intestine on a video monitor. 'This voyage is decidedly non-fantastic.' Garrity was then instructed to roll over on his side by nurse Marge Klogert, who bears no resemblance to Raquel Welch.
