Brad Paisley was quite frank about his new video for "Southern Comfort Zone" after it's debut Monday.    Afterward he went online to answer fan questions about the giraffe in the video and Carrie Underwood.  Asked if he'd ever do another duet with Carrie, he joked, "No. She's horrible to work with. I wouldn't even think about it." Then when a fan asks about the giraffe, he raves about him. "That giraffe was very professional. He was actually really a great giraffe. His name I think is Congo, and he was way better than working with Carrie Underwood. He didn't ever sort of talk back. Even if he had kicked me, it would be still better than working with Carrie Underwood." And when someone brought up the giraffe vs.  Carrie battle again and asks who has better legs, Brad joked, "The giraffe. Totally."   CMT reports the video features Brad running through eight countries in eight days (they flew 10,000 miles to shoot this) for an effect he calls "The Bourne Identity meets Green Acres."   Read more here.
