Emma, my wife, draws butts on everything. If I leave a notebook out in the evening, odds are there will be a crude butt drawn on the open pages by morning. Clean chalkboard? Not for long. Butt. Just as Eve couldn't resist the apple, Emma cannot resist the booty.
This strange happening led to a rather serious thought one day. As humans, it's in our nature to make things our own, even if that means we compromise something else. So naturally, I ruined a Magritte painting.
