Here are some more "Why Did The Chicken Cross the Street" answers submitted by Playwright Anne Wycoff who notes she’s merely rearranged the true words of these famous people. 

Shakespeare:
To cross, or not to cross, that is the question;
Whether ’tis nobler in the mind to stay
The smash and squish of outrageous traffic,
Or to take wings against a road of cars,
And by opposing, cross them.

Robert Burns:
The best laid schemes of chickens an’ cars
Often go awry.

Carman Bliss:
Set me the road to cross, in which I can put my wing,
my beak, my claw, of my very self, 
and it is a road to cross no longer, it is joy;
It is roadkill. And It is the reason why I cross the road.

Mark Twain:
The miracle, or the power, that elevates the few brave chickens to cross the road, is to be found in their egg laying, flight and stupidity under the promptings of a winged, driven spirit.

That, and the fact that their brains are the size of my pinky finger nail, will ensure their unfortunate demise.

Louisa May Alcott:
As a chicken, I am no longer afraid of roads, for I am learning how to drive a car and join my brothers in quest of becoming Foster Farms chickens.

Henry David Thoreau:
Cowardly chickens suffer the desire to cross, heroic chickens, though some be dead, enjoy the thrill of crossing the road of life.

Toni Morrison:
Birth, life and death:  Each took place on the hidden side of the road as an egg, a chick and an unfortunate encounter with a Harley Davidson.

Edgar Allan Poe:
Deep into the dark road peering, long I clucked there, wondering, fearing, doubting, dreaming dreams no chicken ever dared dream before.

Pearl S. Buck:
None who have always been on the other side the road, can understand the terrible, facinating power of the hope of crossing the road to those who are on the  wrong side of the road.

Mahatma Ghandhi:
The difference between crossing the road and being capable of crossing the road would suffice to solve most of the  chicken coups problems.

Erma Bombeck:
What’s wrong with you chickens?  Would you stop laying eggs if you realized that you have wings?  You don’t have to cross the road.  You can fly over it!

Anne Wycoff:
We are always trying to cross the damn road and not appreciate the side of the road we are on.
