You would think becoming the most famous fan base in American sports — and getting your name printed in the Guinness Book of World Records for lowdest crowd noise (twice) — would have you feeling pretty good about yourself. Add to that the fact that you cheer for a team that sure looks ready to make a serious Super Bowl run, and you're probably already making plans for the parade. And when your fame crosses over into music (Dr. Dre of all people!) . . . well, now you're just livin' the dream, right?
