Tired Writing

Heard it on the street (maybe it was on the web): the best writing is done when tired. Can you believe this? I mean, if your brain is dead and want to write something deep, what would you write about? How about this, "The deepness of the deep ocean reached the profound waters of the long and dark deep." Is this deep enough? How about something like this, "Dillon the cat said 'meow,' the she-cats loved it and replied, 'meow, meow.' and that turned Dillon on. He danced the cat dance until they melted--little did they know, he had already been fixed. 'Meow, meow, meow.'"--this is what I call being brain dead, two neurons writing, one falling sleep.
