It's that dress that gives women an hourglass-figure look... except when it doesn't.

And as long as I'm debasing myself by reading the Daily Mail: Chaz Bono is having trouble rehearsing for "Dancing with the Stars" "because he lacks rhythm."

"What could Chaz Bono and Nancy Grace possibly have in common?"

We shall see!
