===Bonus Tracks===
The original CD release first 200,000 copies included a 3.5" CD with the bonus tracks "Physical" and "Suck" in a small envelope inside the digipak. After discovering that some unscrupulous record store owners were selling the bonus disc as a separate entity, Reznor had the format changed and the EP was re-released as a single CD, with the bonus tracks occupying track numbers 98 and 99. Tracks 7 through 97 all contain 1–3 seconds of dead air, leaving a gap of 1:31–4:33 between "Gave Up" and "Physical (You're So). Reznor has explained why the tracks were released as they were: ''"It was a way to distance them from the other music because it wasn't part of the same mind set. Unfortunately, the risk involved is, with radio being as conservative as it is, I knew they would jump on "Physical" or "Suck" because they're a bit more digestible than the other stuff, so I've tried to make them as obscure as possible."''[http://www.theninhotline.net/archives/articles/xart196.shtml]
In 1995, Nine Inch Nails performed "Physical" live with Adam Ant for two nights in a row [[1995/01/06 New York City, NY|in New York City]]. After Reznor introduced Adam Ant and Marco Pirroni on the second night, Adam Ant proclaimed to the audience, "It's nice to be on stage with the best fucking band in the world."
