Angry, Sad, and Funny?

I've been reading Dave Eggers' A Heartbreaking Work of Staggering Genius, and let me just say - I LOVE IT!  Its probably the strangest book I have ever read because it manages to make me laugh and feel sad at the same time.  It truly is heartbreaking because it is all about how the author watched his parents die of cancer, then had to raise his young brother. However, at the same time, it is hilarious.  Eggers uses humor in ways you wouldn't expect in this depressing story.  For example, when he describes how people tell him what a good brother he is, he includes the voice inflection by writing the phrase out with musical notes.  He also makes up strange names for the dismal meals he and his brother live on, describes how he would lie about how his parents died for the amusement he found in torturing the people who have the nerve to ask, and tells funny ancedotes about practically every aspect of his depressing life.  It is also a very angry book.  Eggers seems to be yelling at the world -  he is constantly upset and looking for change, all the while being funny about the things that have gone wrong.  Based on what I have read so far, I'd say the title is fitting, if conceited.  I really like the authors style and the way the book makes me think about my own situation.  I can't wait to keep reading!
