The garbage man sits on the ground talking to Ratbert. He syas, "...As your consciousness passes through each universe, you tend to follow a line of probability." Ratbert writes this down in a spiral notebook. He says, "Got it." The garbage man says, "And since it's more probable that matter is near other matter, you have the illusion of gravity as your consciousness moves toward the norm." He waves his arm in the air to demonstrate. The garbage man says, "Did you get all that, Ratbert?" Ratbert says, "Hey, I'm not stupid. Does this Norm guy have a last name?"
