Our mother, in her infinite wisdom, wanted us to explore the world of art. So we spent much of our formative years wandering through museums, scratching our heads.

"We could have painted this!", we kept saying. Kazimir Malevich's famous Black Square was the biggest offender.

"Sure, you could have," our mother replied. "But you'd have to think of it first."

Take dadaism, for instance. It's out there, to say the least. Duchamp's urinal? Janco's bishop dress? Duchamp's mustache on the Mona Lisa? Janco's... mustache on the Mona Lisa? (Well, they are different types of mustaches!) Is that even art? Isn't it all just... nonsense?

Oh, it might be nonsense. But someone had to think of that nonsense first!

Score one for our mother...
