WATCH: Vulture's Head Caught Up Pig's Butt

The encounter gives new meaning to the phrase "pigging out."

Animals sometimes get their heads stuck in small spaces, but the results aren't always this crappy.

A vulture got more than it bargained for when it started pigging out on this dead swine's anus.

The trending video originally appeared on YouTube in April 2014 and shows the bird struggling to free itself from the pig's cavity. It resurfaced October 16, when posted a copy of the video on Facebook that went viral, positioning the image as a visual metaphor for the forthcoming presidential election.

Funny as it may seem, the encounter also highlights how difficult it is for stuck animals to escape. Fortunately, the vulture was able to free itself within an hour, according to the YouTube video blurb.

Other animals are not always so lucky. Recently, The Huffington Post detailed how Yoplait cups can be lethal for skunks, as they are the perfect shape to trap a the small animal's head. General Mills, the marketer of Yoplait in the U.S., encourages consumers to crush cups after use to protect wildlife.
