To remember the last stand of General Custer, the U.S government decide to enlist the talents of a local artist to help capture the famous battle.
So the artist goes to work, and spends days painting the massive mural.
The big day comes and all the generals are there, waiting to see the unveiling. The artist gives his speech and unveils the masterpiece, to show Jesus on the cross and hundreds of Indians all having sex.
The crowd is gob-smacked by the painting and demand the artist tell them why he has painted such an atrocity. Calmly, the artist takes the stand and explains that the painting represents Custer's last words,
"Jesus Christ, look at all the fucking Indians!".
