Dogs laugh, but they laugh with their tails. And a tail is an awkward thing to laugh with, as you can see by the way they bend themselves half double in extreme hilarity trying to get that rear-end exuberance forward into the main scene of action. What puts man on a higher stage of evolution is that he has got his laugh on the right end.
