It seems like my favorites are always the ones that nobody else likes or understands... or the ones where the joke is so obscure that you have to be a fan of three or four random obscure things in order to get it. In this case, you need to be a fan of surrealist photographer Man Ray, and the 1941 film The Man Who Came to Dinner. And you need to REALLY be a fan of the film to figure out what in this painting is taken from the film!
But I think it's one that, assuming you DO know about the artist & the movie, will give you a good chuckle :)
