Dawn Of The Desert Mule Deer
Ross quoted MULEY in John Ford's 1940 film THE GRAPES OF WRATH:
The rest of my fambly set out for the west - there wasn't nothin' to eat - but I couldn't leave. Somepin' wouldn't let me. So now I just wander around. Sleep wherever I am. I used to tell myself I was lookin' out for things, so when they come back ever'thing would be all right. But I knowed that wan't true. There ain't nothin' to look out for. And ain't nobody comin' back. They're gone - and me, I'm just an 'ol graveyard ghost - that's all in the world I am.
