The Daily Show with Jon Stewart Presents Earth (The Book): A Visitor's Guide to the Human Race - is Awesome and uber funny.  I thought I would mention it because it would be a great Christmas gift for just about anyone.  It is packed full of fun tidbits from history to culture of the human race.  But then I love John Stewart's show... it is the only way I get any news on the States of any worth.  Wish we had a Canadian Daily Show!
