Of mice and rocks

Place at your left hoof
A rock.
Place at your right hoof
A mouse.
If you close your eyes for just a minute,
Which of these will remain?

The mouse has hurried away
Eager to feed
Eager to breed
Eager to live life quickly
Before the claws and the teeth
Bring life to an end

But the rock
Waits at your left.
It will see billions of mice
And millions of ponies
Before it becomes dust.
Listen, then, to the rock.
