Meet Joe Black1998

William Parrish:
[Walking along a crowded sidewalk] You know, I got to thinking. With you here and seemingly occupied, how's your work going, I mean, elsewhere?

Joe Black:
While you were shaving this morning, you weren't just shaving.

William Parrish:
What do you mean?

Joe Black:
You were hatching ideas, making plans, arriving at decisions, right?

William Parrish:
Yeah, I guess so

Joe Black:
So you get the concept. While part of you is doing one thing, another part of you is doing another, perhaps even attending to the problems of your work. Correct?

William Parrish:
Of course

Joe Black:
So you understand the idea. Congratulations, Bill. Now multiply that by infinity, take that to the depth of forever, and you still will barely have a glimpse of what I'm talking about. [Bill stops, Joe keeps walking, Bill takes Joes arm and stops him from getting hit by a car...again]
