Tim: The point is, to John Q Primitive Man, this was his source of fire. They would try to get a spark going, rubbing like this, to see if they could get the kindling moving.
Al: Well, you should be careful, because you could start a fire.
Tim: Like I'm really gonna start a fire with sticks like this. You can't get a spark...
Al: Tim...
Tim: Al... Al...
Al: You're on fire.
Tim: Indeed I am, Al, and, you know, I've done this to teach the kids an important lesson - don't play with sticks. They can put your eye out or ignite your forearm. Al, could you help me out?
