<H2>Why Did the Chicken Cross the Road?</H2>
<br>
KINDERGARTEN TEACHER: To get to the other side
<br><br>
PLATO: For the greater good.
<br><br>
ARISTOTLE: It is the nature of chickens to cross roads.
<br><br>
KARL MARX: It was a historical inevitability.
<br><br>
TIMOTHY LEARY: Because that's the only trip the establishment could let it
take.
<br><br>
RONALD REAGAN: I forget.
<br><br>
CAPTAIN JAMES T. KIRK: To boldly go where no chicken has gone before.
<br><br>
HIPPOCRATES: Because of an excess of phlegm in its pancreas.
<br><br>
LOUIS FARRAKHAN: The road, you see, represents the black man. The chicken
<br>'crossed' the black man in order to trample him and keep him down.
<br><br>
MARTIN LUTHER KING, JR.: I envision a world where all chickens will be
<br>free to cross roads without having their motives called into question.
<br><br>
MOSES: And God came down from the Heavens, and He said unto the chicken,
<br>"Thou shalt cross the road." And the chicken crossed the road, and there
<br>was much rejoicing.
<br><br>
RICHARD M. NIXON: The chicken did not cross the road. I repeat, the
<br>chicken did NOT cross the road.
<br><br>
FREUD: The fact that you are at all concerned that the chicken crossed
<br>the road reveals your underlying sexual insecurity.
<br><br>
DARWIN: Chickens, over great periods of time, have been
<br>naturally selected in such a way that they are now genetically
<br>dispositioned to cross roads.
<br><br>
EINSTEIN: Whether the chicken crossed the road or the road moved beneath
<br>the chicken depends upon your frame of reference.
<br><br>
BUDDHA: Asking this question denies your own chicken nature.
<br><br>
ERNEST HEMINGWAY: To die. In the rain.
<br><br>
ANDERSEN CONSULTING: Deregulation of the chicken's side of the road was
<br>threatening its dominant market position. The chicken was faced with
<br>significant challenges to create and develop the competencies required
<br>for the newly competitive market. Andersen Consulting, in a partnering
<br>relationship with the client, helped the chicken by rethinking its
<br>physical distribution strategy and implementation processes. Using the
<br>Poultry Integration Model (PIM), Andersen helped the chicken use its
<br>skills, methodologies, knowledge, capital and experiences to align the
<br>chicken's people, processes and technology in support of its overall
<br>strategy within a Program Management framework. Andersen Consulting
<br>convened a diverse cross-spectrum of road analysts and best chickens
<br>along with Anderson consultants with deep skills in the transportation
<br>industry to engage in a two-day itinerary of meetings in order to
<br>leverage their personal knowledge capital, both tacit and explicit, and
<br>to enable them to synergize with each other in order to achieve the
<br>implicit goals of delivering and successfully architecting and
<br>implementing an enterprise-wide value framework across the continuum of
<br>poultry cross-median processes. The meeting was held in a park-like
<br>setting, enabling and creating an impactful environment which was
<br>strategically based, industry- focused, and built upon a consistent,
<br>clear, and unified market message and aligned with the chicken's mission,
<br>vision, and core values. This was conducive towards the creation of a
<br>total business integration solution. Andersen Consulting helped the
<br>chicken change to become more successful.
