Psychology: Definition Of Madness

There's a frequently quoted definition of madness: "Doing the same thing over and over again and expecting different results". The saying is variously attributed to Benjamin Franklin and Einstein.

Maybe I'm crazy, but I see that as a definition of stupidity.

My definition of madness is to wrap a vacuum cleaner hose around your waist, put an aluminium pie plate on your head, and say "Look at me! I'm Laverne and Shirley!"
