The one that I find interesting that's similar is WICA. The actual line is, "I'm a loser and a user". Then live he changed it to "a drug user" fairly early on. Then he changed it back, but after rehab, switched back to "drug user". It almost felt like a 12 step type thing to me. Then it went back to just "user" during RevRad. There was one performance this year where he switched it back to "drug user" again. Just found that interesting.
