Answer:
Two men walk into a restaurant. One man orders H2O. The second man says, “I will have H2O too.” The second man dies. How come the second man dies?
Dies half its life. Lives the rest. Dances without music. Breathes without breath.
It cannot be seen, cannot be felt, Cannot be heard, cannot be smelt. It lies behind stars and under hills And empty holes it fills. It comes first and follows after, Ends life, kills laughter.
I am so simple that I can only point. Yet I guide men all over the world.
Take one out and scratch my head, I am now black but once was red.
