The Zax

One day, making tracks
 In the prairie of Prax,
 Came a North-Going Zax
 And a South-Going Zax.
 And it happened that both of them came to a place
 Where they bumped. There they stood.
 Foot to foot. Face to face.
 "Look here, now!" the North-Going Zax said, "I say!
 You are blocking my path. You are right in my way.
 I'm a North-Going Zax and I always go north.
 Get out of my way, now, and let me go forth."
 "Who's in whose way?" snapped the South-Going Zax.
 "I always go south, making south-going tracks.
 So you're in MY way! And I ask you to move
 And let me go south in my south-going groove.
 Then the North-Going Zax puffed his chest up with pride.
 "I never," he said, "take a step to one side.
 And I'll prove to you that I won't change my ways
 If I have to keep standing here fifty-nine days!"
 "And I'll prove to YOU," yelled the South-Going Zax,
 "that I can stand here in the Prairie of Prax
 For fifty-nine years! For I live by a rule
 That I learned as a boy back in South-Going School.
 Never budge! That's my rule. Never budge in the least!
 Not an inch to the west! Not an inch to the east!
 I'll stay here, not budging! I can and I will
 If it makes you and me and the whole world stand still!"
 Well... Of course the world didn't stand still. The world grew.
 In a couple of years, the new highway came through
 And they built it right over those two stubborn Zax
 And left them there, standing un-budged in their tracks.
