I'm back. - which reminds me of a story I just heard:
Steven Spielberg was making a movie about the lives and times of famous composers. He was in the casting process and had Sylvester Stallone and Arnold Schwarzenegger in for an interview.
Stallone was quite excited about the film and asked, "Can I play the part of Mozart? I've always wanted to play Mozart."
Spielberg reluctantly agreed. He then asked Arnold if he had a particular character in mind.
Arnold fixed him with a steely gaze and said, "I'll be Bach."
