FREDERICK, MDTwo days before his scheduled colonoscopy, Barry Feldman, 47, told his wife Joyce he was "kinda excited" by the idea of a camera taking internal pictures of him, sources reported Tuesday. "I'm a little nervous about the test results, but it sure is amazing that they'll be taking photos with a camera the size of a pencil eraser!" Feldman said. "I talked to the doctor, and he said I'll be able to watch the whole thing on a monitor. He said they can even make me a video tape!" Feldman added that he hopes he doesn't pass out from the pain and miss something.
