Doggie Gymnast?

My sister, Molly, now seems to have a unique talent.  Yesterday, she came in from romping around outside in the backyard and she hopped up on the loveseat in the living room. The next time I looked, she was lying down, all stretched out, and her back legs were resting on the arm of the loveseat and her front legs were resting on the arm of the couch. This doesn’t sound particularly unusual, but since the couch and the loveseat are perpendicular to each other and they are about six inches apart, Molly was actually stretched out over thin air and her middle wasn’t touching either piece of furniture!

What is she, some kind of doggie gymnast?!!  You’d never catch me stretched out over thin air.  I’d go splat on the floor!!
