In Montana, on the sight where Custer and his men had their asses handed 
to them by the Sioux, a huge mural is to be painted. The artist insists on 
complete secrecy.
When the mural is unveiled it shows an orgy of naked Indians screwing all 
over the prairie, and in the center a cow with a halo. The artist says the 
mural is a rendering of Custer's final thoughts - "Holy cow! Look at all 
them fuckin' Indians!"
