The best answers I found around the web to this age old question: Why did the chicken cross the road? No, really, why?
Philosophers and Theologians
Kierkegaard: Just because a chicken crosses the road it does not mean he is on the other side
Tillich: The chicken had the courage to be on the other side of the road
Hebrew writer: The LORD made his road straight.
Descartes: I cross; therefore, I am.
Job: Consider the chicken, Were you there when it first crossed the road?
