Art Appreciation - Three Black Men (nsfw)

At the National Art Gallery in Dublin, a husband and wife were staring at
a portrait that had them completely confused. The painting depicted 3 black
men totally naked, sitting on a bench. Two of the figures had black penises,
but the one in the middle had a pink penis.

The curator of the gallery realized that they were having trouble interpreting
the painting and offered his personal assessment. He went on for over half
an hour explaining how it depicted the sexual emasculation of African
Americans in a predominately white, patriarchal society. 'In fact', he pointed
out, 'some serious critics believe that the pink penis also reflects the cultural
and sociological oppression experienced by gay men in contemporary society'.

After the curator left, an Irishman approached the couple and said, 'Would
you like to know what the painting is really about?'
'Now why would you claim to be more of an expert than the curator of the
gallery', asked the couple?
'Because I am the artist, who painted the picture,' he replied. 'In fact, there are
no African Americans depicted at all. They're just three Irish coal miners.
The guy in the middle went home for lunch.'
