I was doing an image search for Lascaux cave paintings this mornings, and I ran across this cartoon... :D
Compare with...
Before the fall when they wrote it on the wall
When there wasn't even any Hollywood
They heard the call
And they wrote it on the wall
For you and me we understood
--From: "Caves of Altimira," by Steely Dan
Speaking of my inner-caveman, I woke up at the crack of dawn this morning; went down to the water's edge; stalked, killed, and ate, a wild Sausage McMuffin™. I feel so primal, so damned authentic! ;)
