Why did the chicken cross the road at the Holocaust Denier Convention?

The road was paved in the first place by Talmudic Zionists intent on overthrowing Aryan Civilization! The chicken had every right to cross the road. The chicken had every reason to cross the road. Nevertheless, the chicken did NOT cross the road and any evidence to the contrary was planted by Mossad agents. The fact that the chicken was first seen on one side of the road and then on the other side is irrelevant since the road was repaved in accordance with the dictates of the New World Order. The fact that the chicken was seen walking across the road is irrelevant since the witnesses were Jews and under instructions from Rabbi Baba Mezia, President Second Amendment, and Professor Volume C of the Encyclopedia Britannica to mislead the furshlugginer goyim.
