The first time I saw the photo known as "piggy poop balls" was September 2011. It was attached to a tweet with the unremarkable but soon-to-be-famous URL: http://imgur.com/5pXPI

There was something special about this particular gross photo — something different. Piggy poop balls transcends mere scatological humor. It's sublime. It's art. And it spread like wildfire.

Since then, this porcine sadsack with a potty problem has rarely left the collective consciousness of the internet. It has been viewed over 200,000 times, and is used as either as a catch-all punchline or placeholder for something funny, like a photo version of a Rick-roll for Twitter.
