Always so fowl?

Was there ever a point in time when the chicken joke was funny? The original one I mean. The one that has come to represent the quintessential definition of a joke in general, and a bad joke in particular.

Q: Why did the chicken cross the road?
A: To get to the other side.

It’s a reversal technique that gives this joke its intended humor. The setup indicates the chicken had some higher purpose for crossing the road. But the punchline indicates he was crossing the road simply for the purpose OF crossing the road. A modern equivalent of this joke (at least the only one I can think of at 4:00 in the morning as I sit in a production trailer babysitting editors) comes from an episode of Friends.

FRANK: We were down at the courthouse, we were having lunch and we just decided to get married.
PHOEBE: Oh my god, what were you doing at the courthouse?
FRANK: We were having lunch.

The funny reversal idea behind the chicken joke is the same, but once we’re actually old enough and intellectually mature enough to get the punchline, we’ve heard it like a zillion times in some other patently not funny context, making it just “that stupid chicken joke.” Really, the only time anyone ever laughs at the chicken joke is when somebody (not unlike the original joke teller) throws some kind of reversal on the expected punchline.

It can be done via a pun like:

Q: Why did the chicken cross the playground?
A: To get to the other slide.

It can be done with absurdity:

Q: Why did the frog cross the road?
A: Because he was stapled to the chicken.

Or it can be done by applying a third party personality to the punchline:

Q: Why did the chicken cross the road?
A (by Einstein): Whether the chicken crossed the road or the road moved beneath it depends on your point of reference.
A (by Martin Luther King): I envision a world where chickens are free to cross roads without having their motives called into question.
A (by Buddha): To ask this question is to deny your own chicken nature.
A (by Colonel Sanders): Wait, you mean I missed one?

But just where the heck did the original joke come from? And moreover, was there ever a point in time when people found it funny? Like did the first adult to ever hear this joke laugh when he heard it? As I said, the joke has become kind of a stock character of sorts representing all jokes everywhere and all bad jokes specifically. But that iconic status couldn’t have materialized out of thin air. Was it a really popular joke that just got told too much, making people sick of it to the point where they finally started mocking the thing? It must have been based in something somewhere in the past. Catch phrases are like that too. We say them and we know what they mean, but they don’t actually make sense in our modern context.

Example: “Close but no cigar.”

Heh? What the heck does a cigar have to do with guessing the wrong answer? Well, fairground games used to give away cigars as prizes. So when a patron missed the ring toss by an inch, the guy running the game would let loose with a phrase that actually meant something in contemporary context. Even though that context has disappeared over the years, the phrase still holds meaning.

Likewise, even though the chicken joke is no longer funny, we still recognize it, not only as a joke, but as THE joke. But where? When? Why? How did this particular joke earn such dubious longevity?

And moreover… why a chicken?
