If you look back far enough in anyone's life, you're going to find some pretty embarrassing stuff.  Nine Inch Nails is no exception to that rule, as evidenced in this video of their performance of Down In It, on Dance Party USA.

 

Man, the 1980's were not a good time for anybody.  I know people bitch about how much music and pop culture suck now a day, but things were awful in the 80's.  I mean the NIN performance is pretty good, but look at the audience's clothes, hair, and dance moves.  Awful.
