These three books are all biographies but they are written humoursly.

Loser Goes First : My Thirty-Something Years of Dumb Luck and Minor Humiliation  Written by Dan Kennedy
 This book is about Dan's place in the world, and all the many, many different jobs along the way.
Clinton & Me: A Real Life Political Comedy  Written by Mark Katz
  This book is Mark's life but mainly his career as a comedy writer for Bill Clinton during his stay in the White House.
Lost In Place : Growing Up Absurd in Suburbia  Written by Mark Salzman
  This is the least funny of the three but hilarous none the less.  This one is about growing up in the middle of no where.

I suggest you read them in the order I list them.
