My dog has run into a wall or two and he does this spastic thing where he drags the sides of his body along side a couch and he goes back and forth and all he serves to do is mess up the couch and ruffle his fur
We have the coffee table pretty close to our couch so we can comfortably put our feet on it. Well, the cat will have his butt on the couch, but put his head and front paws on the coffee table, leaving his stomach hanging between them. He will lay there for a few minutes, then fall asleep. When he does that, he just falls right between them onto the floor. It's pretty funny looking and he does it all the time.
