if you had only one song to convince someone to listen to nin

I got a friend whos taste is extremely similar to mine. I really want him to get into nin since I'm a massive fan and I think he would really enjoy nin if he gives it a few listens. However I want the first song I show him to really get across everything awesome about nin. I cant decide on a song tho, so if you had to convince someone of how great nin is and could only show them one song, which one would it be?
