Why did the chicken cross the road? 

• Plato: For the greater good.
• Karl Marx: It was a historical inevitability.
• Machiavelli: So that its subjects will view it with admiration, as a chicken which has the daring and courage to boldly cross the road, but also with fear, for whom among them has the strength to contend with such a paragon of avian virtue? In such a manner is the princely chicken's dominion maintained.
• Hypocrites: Because of an excess of light pink gooey stuff in its pancreas.
• Jacques Derrida: Any number of contending discourses may be discovered within the act of the chicken crossing the road, and each interpretation is equally valid as the authorial intent can never be discerned, because structuralism is DEAD, DAMMIT, DEAD!

• Albert Einstein: Whether the chicken crossed the road or the road crossed the chicken depends upon your frame of reference.
• Aristotle: To actualize its potential.
• Buddha: If you ask this question, you deny your own chicken-nature.
• Howard Cosell: It may very well have been one of the most astonishing events to grace the annals of history. An historic, unprecedented avian biped with the temerity to attempt such an herculean achievement formerly relegated to homo sapien pedestrians is truly a remarkable occurence.
• Salvador Dali: The Fish.
• Darwin: It was the logical next step after coming down from the trees.

• The Godfather: I didn't want its mother to see it like that.
• Keats: Philosophy will clip a chicken's wings.
• Blake: To see heaven in a wild fowl.
• Othello: Jealousy.
• Dr. Johnson: Sir, had you known the Chicken for as long as I have, you would not so readily enquire, but feel rather the Need to resist such a public Display of your own lamentable and incorrigible Ignorance.
• Mrs. Thatcher: This chicken's not for turning.
• Supreme Soviet: There has never been a chicken in this photograph.
• Oscar Wilde: Why, indeed? One's social engagements whilst in town ought never expose one to such barbarous inconvenience - although, perhaps, if one must cross a road, one may do far worse than to cross it as the chicken in question.
• Kafka: Hardly the most urgent enquiry to make of a low-grade insurance clerk who woke up that morning as a hen.

• Shelley: 'Tis a metaphor for the pursuits of man: though 'twas deemed an extraordinary occurrence at the time, still it brought little to bear on the great scheme of time and history, and was ultimately fruitless and forgotten.
• Tolkien: Chickens are respectable folk, and well thought of. They never go on any adventures or do anything unexpected. One fine spring day, as the chicken wandered contentedly around the farmyard, clucking and pecking and enjoying herself immensely, there appeared a Wizard and thirteen Dwarves who were in need of a chicken to share in their adventure. Reluctantly she joined their party, and with them crossed the road into the great Unknown, muttering about how rude the Dwarves were to take her away on such short notice, without even giving her time to brush her feathers or fetch her hat.
• Hussie: He didn't, he died four pages after being introduced.
