"Whether people grow fat by joking, or whether there is something in fat itself which predisposes to a joke, I have never been quite able to determine; but certain it is that a lean joker is a rara avis in terris"

Edgar Allan Poe-- From his short story Hop-Frog

I too have always wondered why I am not grouch of the first order. One day I will weigh enough to make jokes. One day. Look out belly here I come.
