World problems solved, baby!
According to one Reddit group, the woman in the final shot is supposed to be Paris Hilton. Even though it isn't an exact match, the slight inaccuracy is actually understandable -- you'd better replicate her by stretching plastic bags over a bored sparrow's skeleton (but only if the bags previously housed cocaine). Still, that is one conventionally attractive pig.
... I know you're waiting for an "And the swine, too!" punchline, but know that it will never come. I save my Hilton loathing for the banal way she slouches through life.
Is this series an art project? Well ... obviously it is, but did any of this happen? Did a pig just become a decapitated blonde? The source is a magazine called Hurt You Bad, but good luck finding a copy. Like Necronomicons, it's limited to a select run and on display only to those whose magical will may resist its dark urgings.
The creator could be a plastic surgeon or it could be an artist or it could be a maniac. If you read through that Reddit thread I linked to earlier, one person suggests that the pig's head is being replaced by modeling clay (or maybe wax) toward the end, and that makes a lot of sense. The shenanigans of its faux transformation aside, isn't the greater point about what it means for women? And society? And pigs with body issues? Is this why those cartoon pigs are always so happy on butchers' logos? Because they're not Paris Hilton?
