A couple are at an Art exhibition and they are looking at a portrait.

The picture depicts 3 very black, very naked men sitting on a park bench; 2 have a black penis and the one in the middle has a pink penis.

As the couple are looking somewhat puzzled at the picture, the Irish 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 two have a black penis."

The Irish artist says "Oh you are misinterpreting the painting. They are not African men, they are Irish coal miners, and the one in the middle went home for lunch."
