At an art exhibition two women were staring at a painting entitled, "Home for Lunch".
The painting was of three very naked, and very black men, sitting on a park bench. What was unusual was that the men on both ends of the bench had black penises, but the man in the middle had a very pink penis. The two women were standing there, staring at the picture, scratching their heads and trying to figure this out. The artist walked by and noticed the women's confusion. "Can I help you with this painting?" he asked.
"Well, yes" said the one woman. "We were curious about the picture of the black men on the bench. Why does the man in the middle have a pink penis?"
"Oh," said the artist. "I'm afraid you've misunderstood the painting. The three men are not African-Americans, they're coal miners, and the fellow in the middle went "Home for Lunch."
