Anti-Joke Chicken is an image macro series featuring an image of a hen accompanied by a top line of text that sounds like the introduction of a joke, but the bottom line provides an unexpected anticlimax. The chicken is centered within a typical advice animal starburst background.
Anti-humor existed well before the Internet was invented. While anti-humor comes in many forms, one of the most common is the one used in this meme: a joke-like setup followed by a non-punchline. This forms a sort of meta-joke in which ironic humor is found in the lack of any standard form of humor. One of the most well-known anti-humor jokes is the classic:
Q:Why did the chicken cross the road?
A:To get to the other side!
Dating back at least to the mid-1800s, this joke contains no inherent humor within the punchline, and is likely a partial inspiration for this meme.
The above is the original photo on which the image macro was based. It was taken by the owner of the hen, professional ophthalmic photographer Marshall E. Tyler, at his home in North Carolina.
