Willem's mother Niki was trying to hurry Willem out the door for a busy day ahead. Willen began moving, very dramatically, in slow motion across the living room.

With some frustration, Niki said: "Willem, what are you doing?"

Willem: "I have to be careful how I move...because with every step I take, I'm making a new me!"

Niki: "What does that mean?"

Willem: "There's a whole trail of Willems following me. But I can make them get back inside me anytime I want to. Right now, all the old Willems are sitting out in the car waiting for me...so let's go!"

And out he went.
