In this episode, the CIA airs its dirty laundry -- I hope they know to use cold water on bloodstains. Plus, I'll look at the last book in the Harry Potter series and find out how this young wizard magically makes his face appear on all cereal boxes. Then, my guest Daniel Gilbert has written a book on finding happiness -- he's gonna need it after this interview. Being me is a fulltime job and I've never missed a day. This is The Colbert Report.
