Gibson, the world's tallest dog.At 7 feet long and with a shoulder height of over 42¡í, this Great Dane is a monster. He's shown here with actor Michael Clarke Duncan - star of "The Green Mile" and a tall man himself, at 6¡ì 5¡í - and Gibson's owner, Sandy.It's good luck Gibson is friendly because he could do a lot of damage if not.
