A Matter of Black (and White) Humour.

Have you noticed that traffic cones the world over are red and white? It’s a matter of definition; the traffic cone is definitively a red and white object, right?

Not always, it seems. I was walking past an undertaker’s premises recently and they had traffic cones set up to discourage parking in the space reserved for the hearse. Their traffic cones were black and white.

Now, I do understand the reasoning behind this chromatic aberration. What I don’t understand is why I found it funny.
