The curator of a Western art museum commissioned a local artist to paint a mural-sized painting of Custer's Last Thought. The artist was told to make it highly symbolic of Custer's mindset during the debacle at Little Big Horn.
Deep in thought, the artist went to her studio. After many false starts, she proceeded to paint an enormous oil painting. Finally, after many months of work, the painting was unveiled for the curator. In the foreground, a beautiful crystalline blue lake with a single fish leaping. Around the fish's head is a halo. In the background, the hills and meadows are covered with naked Native American couples copulating.
The curator is both disgusted and baffled by what he sees. In a rage he turns to the artist and asks, "What the hell has this got to do with Custer's Last Thought?"
The artist replied, "Well, the way I see it, Custer's Last Thought had to have been: "Holy Mackerel! Where did all these fucking Indians come from?'"
