That girl I brought home from the bar last night was a total freak. We did the nine hole mambo, all three holes three times, then I finished on her face.

Nine Inch Nails 

Nine Inch Nails was a one-man-band fronted by Trent Reznor. With influences such as Ministry, he successfully debuted with his first full-length studio album "Pretty Hate Machine." Fed up with greedy record label bullshit, he made his own label, and released the highly successful Grammy-Award winning Broken EP. He then peaked with his follow-up, The Downward Spiral, getting huge hits such as Closer, March of the Pigs, and Hurt. This was followed by cocaine abuse and rehab for about 5 years, until he returned with an album some find okay, and some find brilliant "The Fragile." He then went on to release "With Teeth" "Year Zero" and his final album "The Slip." He has just recently found new commercial success as a movie soundtrack artist, mainly recognized for winning an Oscar with Atticus Ross for the (also award winning) film, the Social Network.

Black Guy: Whats your favorite Nine Inch Nails song?

Me: Just about anything from Broken to the Downward Spiral. He released some pretty good stuff afterward though.

Approaching time to go to class
Gentleman 1: "Nine-Eleven?"
Gentleman 2: "Let's roll."

At a horrible party
Gentleman 1: "Nine-Eleven; let's roll."
