A couple is attending an art exhibition and they are looking at a portrait that has them a little taken aback. The picture depicts three very black, very naked men sitting on a park bench. Two of the men have a black penis and the one in the middle has a pink penis.
As the couple is looking somewhat puzzled at the picture, the artist walks by and says, "Can I help you with this painting? I'm the artist who painted it."
The man says, "Well, we like the painting but don't understand why you have 3 African men on a bench and the one in the middle has a pink penis while the other 2 have a black penis."
The artist says, "Oh! You are misinterpreting the painting. They are not African men. They are coal miners and the one in the middle went home for lunch."
