IRISH ARTIST

A couple is attending an Art exhibit and they are looking at a portrait that has them taken aback. The picture depicts three very black, very naked men sitting on a park bench; two 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 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 threeAfrican 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're not African men, they are Irish coal miners and the one in the middle went home for lunch."
