From an Atlantic interview with Bill Clinton (reprinted by, yes, Free Republic):
[Q: Would you like to write a number of books, like Carter or Nixon?] I'd like to write more, if people like this one. This book will not be as policy-oriented as a lot of the books I could write. I've actually been talking to John Kenneth Galbraith about writing a book about American government. I'd be very interested in doing it with him. I think he thinks my autobiography a little frivolous and wants me to get that over with so I can do something serious and worthwhile. [This last sentence delivered wryly.]
Clinton almost wrote a book with Galbraith? That would've been...something. I'm not quite sure what, but definitely something.
