An eccentric billionaire wanted a mural painted on his library wall, so he called in an artist. Describing what he wanted, the billionaire said, "I am a history buff, and I would like your interpretation of the last thing that went through Custer's mind before he died. I am going out of town on business for a week, and when I return I expect to see it completed."

Upon his return, the billionaire went to the library to examine the finished work. To his surprise he found a painting of a cow with a halo. Surrounding this were hundreds of Indians in various sexual positions.

Furious, he called the artist in. "What the hell is this?" screamed the billionaire.

"Why that's exactly what you asked for," said the artist smugly.

"No! I didn't ask for a mural of pornographic filth. I asked for an interpretation of Custer's last thoughts!"
