OK you asked. http://en.wikipedia.org/wiki/Why_did_the_chicken_cross_the_road%3F
"Why did the chicken cross the road?" is one of the oldest and most famous riddles still in use in the English language. [citation needed] The most common answer is "To get to the other side." When asked at the end of a series of other riddles, whose answers are clever, obscure, and tricky, this answer's obviousness and straight-forwardness becomes part of the humor.
Origin
This riddle's origins are obscure. Its first known appearance in print occurred in 1847 in The Knickerbocker, a New York monthly magazine: [1]
- ...There are 'quips and quillets' which seem actual conundrums, but yet are none. Of such is this: 'Why does a chicken cross the street?['] Are you 'out of town?' Do you 'give it up?' Well, then: 'Because it wants to get on the other side!'
This riddle's humor comes from the fact that its answer is expected to be funny, but is not. [2]
The joke may already have become widespread by the 1890s, when a variant version appeared in the magazine Potter's American Monthly: [3]
- Why should not a chicken cross the road?
- It would be a fowl proceeding.
This riddle inverts the question, asking why a chicken should not cross the road. The answer ("It would be a foul proceeding") confounds the noun fowl with the homophonic adjective foul and plays on two different senses of proceeding. Since a chicken in the act of crossing might be called "a fowl, proceeding," the joke makes a pun by calling the action "a foul proceeding," hence something that should not be done. Variations
There are many riddles that assume a familiarity with this well-known riddle and its answer. One class of variations enlist a creature other than the chicken to cross the road. For example, a turkey or duck crosses "because it was the chicken's day off." Another variant: "Why did the dinosaur cross the road?" "Because chickens weren't invented yet."
Punning variations include "Why didn't the skeleton cross the road?" to which the answer is "Because he had no guts," or "He had no body to cross with him." "Why did the chicken cross the road halfway? To 'lay it on the line'." Or one might change the circumstances and the word "side", such as "Why did the chicken cross the playground? To get to the other slide."
Another class of variations, designed for written rather than oral transmission, employs parody by pretending to have notable individuals or institutions give characteristic answers to the question posed by the riddle. Variants on this theme are virtually endless. For example:
Some variations work by elaborating on the circumstances of the event described by the joke. "Why did the chewing gum cross the road?" "Because it was stuck to the chicken's foot." Others employ anti-humor by giving a "rational" answer that is also absurd: "Why did the chicken cross the road?" "Because it had no frontal lobe." Other variants go for shock value: "Why did the dead baby cross the road?" "Because it was stapled to the chicken." But most just set out to amuse like Kermit the Frog's infamous answer to the riddle: "Because an angry Swede was chasing it with a cleaver!"
In the movie Stripes, a reference to the joke occurs in an impromptu marching cadence: "Why did the chicken cross the road? To get from the left ... to the right!"
The joke is reportedly codified into law in at least one municipality. A Quitman, Georgia ordinance prohibits chickens from crossing the road. [4]
In describing his experiences touring with The Residents on the laser disc documentary 20 Twisted Questions, illusionist Penn Jillette stated that one member of the band told this version: "Why did man invent God? To get to the other side."
