Laugh a little
The Eye of the Beholder
Mrs Stein a rich tourist goes to Paris to visit the art galleries. She decides to hire the services of a guide to show her around the Louvre.
"Oh!" said Mrs Stein looking at a painting, "That's a Monet isn't it?"
"No Madame, almost, it's a Manet." replied the guide.
"And that one, it's a Pissaro?"
"Er... no I'm sorry Madame, that's a Monet."
"Oh, I see. Now that one I’m sure of - that's a Picasso isn’t it?"
".... no Madame, that's a mirror."
