Dec 23 1888--After an argument with fellow painter Paul Gauguin, Vincent van Gogh takes a razor and removes a portion of his left ear. Their quarrel regarded the prostitutes in Arles who seemed to prefer Gauguin over Van Gogh; the painter delivered his ear to one Rachel, who preferred Van Gogh. She fainted.
I had a funny commentary to go along with this, and then I thought "Man, what really is there left to say?"
