Normally if something has been on the Tonight Show it's probably not IotD fodder, but I couldn't resist this item about Gibson, the world's tallest dog. At 7 feet long and with a shoulder height of over 42", 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' 5" - and Gibson's owner, Sandy.
It's good luck Gibson is friendly because he could do a lot of damage if not.
