===Meaning===
According to the Filter biography on their official website, former live guitarist [[Richard Patrick]] reportedly received the nickname "Piggy" while in Nine Inch Nails. As well, "Piggies" is a song on The Beatles' 1968 self-titled (or 'white') album, a noted influence on Charles Manson, who scrawled the word "pig" in blood on the front door of the Sharon Tate mansion wherein he and his 'Family' killed Tate and several others on August 8, 1969. The mansion was also where Reznor recorded ''The Downward Spiral'' in 1993-4. Whether or not Patrick or the Tate murders are directly related to this song is unknown, though and Reznor kept the Tate door when he moved to [[Nothing Studios]] in New Orleans.In an interview[http://www.nin-pages.de/2003_Metal_Hammer_April_english.htm], Reznor debunked rumors of song connections to the Tate murders: <blockquote>"I had 'Piggy' written long before it was ever known that I would be in that house. 'March of the Pigs' has nothing to do with the Tate murders or anything like that, I’m not going to say what it is about, but it’s not about that. Yeah, the name of the studio being 'Pig', that was a definite bad taste joke. It was written on the front door at one time, I’ll admit to that."</blockquote>
